Story highlights U.S. begins aid drops to Iraqi town surrounded by ISIS, the Pentagon says 
 
 Syrian Observatory for Human Rights says ISIS has sold Yazidi girls and women 
 
 About 300 have been abducted, the rights group says 
 
 Syria monitors: ISIS sees them as "captives of the spoils of war with the infidels" 
 
 The United States says it has carried out airstrikes and dropped humanitarian aid in the Iraqi town of Amerli to protect an ethnic minority that one official says faces the threat of an "imminent massacre." 
 
 The town of Amerli, which has been besieged by ISIS fighters, is home to many of Iraq's Shiite Turkmen. 
 
 To help the trapped people, the United States has carried out humanitarian airdrops, Pentagon press secretary Rear Adm. John Kirby said late Saturday. 
 
 Australia, France and the UK also participated in the aid drop. 
 
 The U.S. military conducted "coordinated airstrikes" against ISIS targets as part of an effort to support the humanitarian operation, Kirby said. 
 
 Video released by the Iraqi Ministry of Defense was strikingly similar to the scenes of the dire situation faced by the Yazidis, who were trapped on the Sinjar Mountains by ISIS, earlier this month. Dozens of people crowded helicopters, hoping to be rescued. Scores more awaited the arrival life-saving supplies in the scorching summer sun. 
 
 ISIS fighters have surrounded Amerli , 70 miles north of Baquba, since since mid-June. The town's fewer than 20,000 residents are without power. 
 
 "Residents are enduring harsh living conditions with severe food and water shortages, and a complete absence of medical services -- and there are fears of a possible imminent massacre," U.N. High Commissioner for Human Rights Navi Pillay said last week. 
 
 ISIS has called the Shiite Turkmen heretics and vowed to push them out. 
 
 Turkmen are descendants of a Turkic-speaking, traditionally nomadic people, who share culture ties with Turkey. There are Sunni and Shiite Turkmen in Iraq, and they account for up to 3% of Iraq's population. 
 
 Turkmen have been subjected to violence before at the hands of Sunni extremists. 
 
 A truck bomb explosion in 2008 Amerli killed more than 100 people -- an attack that was considered one of the single deadliest attacks of the Iraq War at the time. 
 
 Report: ISIS selling Yazidi women in Syria 
 
 Hundreds of Yazidi women abducted by ISIS have either been sold or handed out to members of the Sunni extremist group, according to an organization that monitors the crisis. 
 
 In the past few weeks, ISIS has "distributed" to its rank and file about 300 female members of the persecuted religious minority, says the Syrian Observatory for Human Rights, a UK-based monitoring group aligned with the opposition in Syria. 
 
 Those women were initially kidnapped in Iraq before being taken to Syria. 
 
 In ISIS' eyes, the girls and women are "captives of the spoils of war with the infidels," the Syria monitors said, claiming that some had converted to Islam so ISIS fighters can marry them. 
 
 SOHR says it could confirm at least 27 cases in which women were "sold and married" for about $1,000 each to ISIS militants in Aleppo and Raqqa suburbs and Al-Hassakah.

 Tens of thousands of Yazidis fled to Mount Sinjar in northern Iraq as ISIS fighters made deadly advances on their villages. They became trapped on the mountain, leading to air drops of water, food and other supplies, and eventually airstrikes to dislodge ISIS from the area. 
 
 Peshmerga forces managed to help most of the Yazidis escape into Iraqi Kurdistan. 
 
 U.S. President Barack Obama declared an end to the ISIS siege at Mount Sinjar on August 15, citing the success of the airstrikes. 
 
 Since early August, nearly 122,600 people in the Sinjar district -- mostly Yazidis -- have taken refuge in Kurdistan, according to USAID 
 
 A U.N. report warned of increasing kidnappings by armed groups in Mosul and the area of Mount Sinjar. 
 
 The U.N. High Commissioner for Refugees (UNHCR) reported that some of the victims reportedly have been forced to convert to Islam and have been trafficked by the terrorist groups inside and outside of Iraq. 
 
 A number of villages in Sinjar remain besieged by ISIS and other armed groups, the refugee agency reported. 
 
 ISIS, which calls itself the Islamic State, was previously referred to as the Islamic State in Iraq and Syria. 
 
 Attacks across Iraq 
 
 At least three Iraqi soldiers were killed Saturday in a suicide car bombing south of Iraq's capital, police said, dealing a blow to the military in that area for a second straight day as government forces fight ISIS militants across the country. 
 
 Seven other soldiers were injured in the attack, which happened at an army checkpoint in Yousifiya, a predominantly Sunni Muslim area about 35 kilometers (22 miles) south of Baghdad, police in Baghdad said. 
 
 It wasn't immediately clear who conducted the bombing. 
 
 The blast came a day after nine Iraqi soldiers and Shiite Muslim militiamen were killed in clashes with suspected ISIS militants in nearby Mahmoudiya, a Sunni Muslim community about 29 kilometers south of Baghdad. 
 
 During the height of Iraq's insurgency last decade following a U.S.-led invasion, Yousifiya and Mahmoudiya, along with the town of Latifiya, made up the Sunni area known as the "Triangle of Death" because it was an al Qaeda stronghold and a lair for criminals. 
 
 Iraqi forces under a Shiite-led regime, as well as ethnic Kurdish forces, have been battling ISIS, which this year took over large portions of northern and western Iraq and eastern Syria for what it calls its new caliphate. 
 
 Well before ISIS made gains, Iraq was beset for years by sectarian violence, with Sunnis feeling politically marginalized under a Shiite-led government since the U.S.-led ouster of longtime leader Saddam Hussein in 2003. 
 
 More U.S. airstrikes 
 
 U.S. forces conducted more airstrikes against ISIS targets near the Mosul on Saturday, according to the U.S. military, destroying a militant fighting position and armed vehicle. 
 
 "The strikes were conducted under the authority to support Iraqi security force and Kurdish defense force operations, as well as to protect critical infrastructure, U.S. personnel and facilities, and support humanitarian efforts," U.S. Central Command said in a press release. 
 
 CENTCOM said it has carried 115 strikes across Iraq. ||||| Keith Alexander, the recently retired director of the National Security Agency, left many in Washington slack-jawed when it was reported that he might charge companies up to $1 million a month to help them protect their computer networks from hackers. What insights or expertise about cybersecurity could possibly justify such a sky-high fee, some wondered, even for a man as well-connected in the military-industrial complex as the former head of the nation's largest intelligence agency? 
 
 The answer, Alexander said in an interview Monday, is a new technology, based on a patented and "unique" approach to detecting malicious hackers and cyber-intruders that the retired Army general said he has invented, along with his business partners at IronNet Cybersecurity Inc., the company he co-founded after leaving the government and retiring from military service in March. But the technology is also directly informed by the years of experience Alexander has had tracking hackers, and the insights he gained from classified operations as the director of the NSA, which give him a rare competitive advantage over the many firms competing for a share of the cybersecurity market. 
 
 The fact that Alexander is building what he believes is a new kind of technology for countering hackers hasn't been previously reported. And it helps to explain why he feels confident in charging banks, trade associations, and large corporations millions of dollars a year to keep their networks safe. Alexander said he'll file at least nine patents, and possibly more, for a system to detect so-called advanced persistent threats, or hackers who clandestinely burrow into a computer network in order to steal secrets or damage the network itself. It was those kinds of hackers who Alexander, when he was running the NSA, said were responsible for "the greatest transfer of wealth in American history" because they were routinely stealing trade secrets and competitive information from U.S. companies and giving it to their competitors, often in China. 
 
 Alexander is believed to be the first ex-director of the NSA to file patents on technology that's directly related to the job he had in government. He said that he had spoken to lawyers at the NSA, and privately, to ensure that his new patents were "ironclad" and didn't rely on any work that he'd done for the agency -- which still holds the intellectual property rights to other technology Alexander invented while he ran the agency. 
 
 Alexander is on firm legal ground so long as he can demonstrate that his invention is original and sufficiently distinct from any other patented technologies. Government employees are allowed to retain the patents for technology they invent while working in public service, but only under certain conditions, patent lawyers said. If an NSA employee's job, for instance, is to research and develop new cybersecurity technologies or techniques, then the government would likely retain any patent, because the invention was directly related to the employee's job. However, if the employee invented the technology on his own time and separate from his core duties, he might have a stronger argument to retain the exclusive rights to the patent. 
 
 "There is no easy black-and-white answer to this," said Scott Felder, a partner with the law firm Wiley Rein LLP in Washington, adding that it's not uncommon for government employees to be granted patents to their inventions. 
 
 A source familiar with Alexander's situation, who asked not to be identified, said that the former director developed this new technology on his private time, and that he addressed any potential infractions before deciding to seek his patents. 
 
 But Alexander started his company almost immediately after stepping down from the NSA. As for how much the highly classified knowledge in his head influenced his latest creation, only Alexander knows. 
 
 In the interview, Alexander insisted that the cybersecurity technology he's inventing now is distinct enough from his work at the NSA that he can file for new patents -- and reap all the benefits that come with them. A patent prohibits any other individual, company, or government agency from using the underlying invention without a license from the patent holder. 
 
 But even if Alexander's new technology is legally unique, it is shaped by the nearly nine years he spent running an intelligence colossus. He was the longest-serving director in the history of the NSA and the first commander of the U.S. Cyber Command, responsible for all cybersecurity personnel -- defensive and offensive -- in the military and the Defense Department. From those two perches, Alexander had access to the government's most highly classified intelligence about hackers trying to steal U.S. secrets and disable critical infrastructure, such as the electrical power grid. Indeed, he helped to invent new techniques for finding those hackers and filed seven patents on cybersecurity technologies while working for the NSA. 
 
 Alexander used his influence to warn companies that they were blind to cyberthreats that only the NSA could see, and that unless they accepted his help, they risked devastating losses. Alexander wanted to install monitoring equipment on financial companies' websites, but he was rebuffed, according to financial executives who took part in the discussions. His attempts to make the NSA a cyber-watchdog on corporate networks were seen as a significant intrusion by government into private business. 
 
 Few, if any, independent inventors have seen such detailed, classified information about the way hackers work and what classified means the government has developed to fight them, all of which gives Alexander a competitive advantage in his new life as a businessman. That insider knowledge has raised eyebrows on Capitol Hill, where Rep. Alan Grayson (D-Fla.) has publicly questioned whether Alexander is effectively selling classified information in exchange for his huge consulting fee. (Bloomberg reported that the figure dropped to $600,000 after the $1 million figure raised hackles in Washington and among computer-security experts.) 
 
 Alexander said that his new approach is different than anything that's been done before because it uses "behavioral models" to help predict what a hacker is likely to do. Rather than relying on analysis of malicious software to try to catch a hacker in the act, Alexander aims to spot them early on in their plots. Only the market will tell whether his approach is as novel as he claims. (One former national security official with decades of experience in security technology, and who asked to remain anonymous, said the behavioral-model approach is highly speculative and has never been used successfully.) 
 
 The former NSA chief said that IronNet has already signed contracts with three companies -- which he declined to name -- and that he hopes to finish testing the system by the end of September. 
 
 "We've got a great solution. We've got to prove that it works," Alexander said. "It will be another way of looking at cybersecurity that gives us greater capabilities than we've had in the past." 
 
 Asked why he didn't share this new approach with the federal government when he was in charge of protecting its most important computer systems, Alexander said the key insight about using behavior models came from one of his business partners, whom he also declined to name, and that it takes an approach that the government hadn't considered. It's these methods that Alexander said he will seek to patent. 
 
 Alexander said that if he determines that he needs to use technology or methods that the NSA has patented, he will pay for a license, including for anything he helped to invent while he was in office and for which he doesn't own the rights. During his time at the NSA, Alexander said he filed seven patents, four of which are still pending, that relate to an "end-to-end cybersecurity solution." Alexander said his co-inventor on the patents was Patrick Dowd, the chief technical officer and chief architect of the NSA. Alexander said the patented solution, which he wouldn't describe in detail given the sensitive nature of the work, involved "a line of thought about how you'd systematically do cybersecurity in a network." 
 
 That sounds hard to distinguish from Alexander's new venture. But, he insisted, the behavior modeling and other key characteristics represent a fundamentally new approach that will "jump" ahead of the technology that's now being used in government and in the private sector. 
 
 Alexander said he was persuaded to start a security business and apply for patents after hearing from potential customers, including company executives, who said they were worried about hackers who could steal or even erase the proprietary data on their companies' computers. Alexander said they were particularly worried about threats like the Wiper virus, a malicious computer program that targeted the Iranian Oil Ministry in April 2012, erasing files and data. 
 
 That will come as a supreme irony to many computer security experts, who say that Wiper is a cousin of the notorious Stuxnet virus, which was built by the NSA -- while Alexander was in charge -- in cooperation with Israeli intelligence. The program disabled centrifuges in a nuclear plant in Iran in a classified operation known as Olympic Games. The United States has never acknowledged its involvement. 
 
 The United States isn't the only government capable of building data-erasing malware. Iran is building a formidable cyber-army, U.S. intelligence officials say, and is believed to be behind a 2012 attack on an oil company in Saudi Arabia that erased data from more than 30,000 computers. Iranian hackers also launched a series of cyberattacks on major U.S. bank websites the same year, intelligence officials say. The strike took Washington by surprise because it was so sophisticated and aggressive. The hackers hijacked data centers consisting of thousands of computers each and used them to flood the bank websites with digital traffic, causing them to crash. 
 
 Brendan Smialowski / AFP ||||| RIYADH, Saudi Arabia -- The king of Saudi Arabia has warned that extremists could attack Europe and the U.S. if there is not a strong international response to terrorism after Islamist extremists seized a wide territory across Iraq and Syria. 
 
 While not mentioning any terrorist groups by name, King Abdullah's statement appeared aimed at drawing Washington and NATO forces into a wider fight against the Islamic State of Iraq and Syria, or ISIS, and its supporters in the region. Saudi Arabia openly backs rebels fighting Syrian President Bashar Assad, but is concerned that the breakaway al Qaeda group could also turn those very same weapons on the kingdom. 
 
 "I am certain that after a month they will reach Europe and, after another month, America," he said at a reception for foreign ambassadors Friday. 
 
 Official Saudi media carried the king's comments early Saturday. 
 
 "These terrorists do not know the name of humanity and you have witnessed them severing heads and giving them to children to walk with in the street," the king said, urging the ambassadors to relay his message directly to their heads of state. 
 
 CBS News correspondent Julianna Goldman reports from Washington that President Obama didn't talk military planning Friday night when he met with Democratic donors, but he said that he understands that Americans are anxious about the growing threat of ISIS, and he acknowledged that it's a dangerous time in the Middle East. 
 
 A day after the president said that he doesn't have a strategy yet for confronting ISIS, also known as the Islamic State of Iraq and the Levant, or ISIL, in Syria, White House press secretary Josh Earnest said Mr. Obama is waiting for his defense secretary to present a plan. 
 
 "There are some who probably would make the case that it's OK to not have a formulated, comprehensive strategy but, just as one pundit I know recently suggested, that we could just go drop some bombs and see what happens," Earnest told reporters Friday. "That is not what the president believes is a smart approach." 
 
 Echoing that message, Pentagon spokesman Adm. John Kirby said the Defense Department doesn't have binders full of plans at any given moment. 
 
 "Planners down in Tampa and planners here in the Pentagon continually refine and change and update planning options for potential military activity," Kirby told reporters Friday. "It is an ongoing effort." 
 
 The U.S. military campaign against ISIS is so far limited to targets in Iraq, but Mr. Obama is considering expanding the mission to also include Syria, where this week he ordered surveillance flights. 
 
 ISIS has been fighting moderate rebels, other extremists and Assad's forces in Syria for nearly three years. Iraq has faced an onslaught by the Sunni extremists and their supporters since early this year, and the country continues to be roiled by instability. 
 
 While providing arms and support to Sunni militants in Syria, Saudi Arabia has denied directly funding or backing ISIS. 
 
 British officials raised the country's terror threat level Friday to "severe," its second-highest level, because of developments in Iraq and Syria, but there was no information to suggest an attack was imminent. The White House has said it does not expect the U.S. to bump up its terrorism threat warning level. 
 
 Saudi Arabia, a major U.S. ally in the region, has taken an increasingly active role in criticizing ISIS. Earlier this month, the country's top cleric described ISIS and al Qaeda as Islam's No. 1 enemy and said that Muslims have been their first victims. State-backed Saudi clerics who once openly called on citizens to fight in Syria can now face steep punishment and the kingdom has threatened to imprison its citizens who fight in Syria and Iraq. 
 
 A decade ago, al Qaeda militants launched a string of attacks in the kingdom aimed at toppling the monarchy. Saudi officials responded with a massive crackdown that saw many flee to neighboring Yemen. In the time since, the kingdom has not seen any massive attacks, though it has imprisoned suspected militants and sentenced others to death. 
 
 Meanwhile Saturday, police in Iraq said a suicide bomber drove his explosives-laden car into an army checkpoint in the town of Youssifiyah, killing 11 people, including four soldiers, and wounding at least 24 people. Youssifiyah is 12 miles south of Baghdad. 
 
 Hours later, a roadside bomb targeting an army patrol killed two soldiers and wounded five in Latifiyah, a town 20 miles south of Baghdad. 
 
 Medical officials confirmed the casualty figures. All officials spoke to The Associated Press on condition of anonymity as they were not authorized to speak to journalists. ||||| Photo 
 
 BEIRUT, Lebanon — Members of the Islamic State in Iraq and Syria have beheaded a Lebanese soldier who was one of 19 captured when militants seized a Lebanese border town for a few days this month. A video of the beheading was posted on social media sites on Saturday. 
 
 The soldier, recognizable as Ali al-Sayyed, a Sunni Muslim from northern Lebanon, was shown blindfolded with his hands tied behind his back, writhing and kicking the dusty ground as a militant announced that he would be killed. Another militant then beheaded him. 
 
 The Lebanese Army declined to comment, but security officials and members of ISIS confirmed the beheading. 
 
 Hours later, the group posted a second video showing nine other soldiers begging for their lives — urging their families to stage street protests to demand that Lebanese officials release Islamist prisoners, so the soldiers would not be killed. 
 
 Earlier this month, Syrian militants, including members of ISIS and the Nusra Front, battled the Lebanese Army after a rebel commander, Imad Ahmad Jomaa, was arrested in Arsal, Lebanon, a town near the Syrian border. Mr. Jomaa was a commander in the Nusra Front who switched his affiliation to ISIS but remained popular among the Nusra fighters.

 The militants seized Arsal for five days before withdrawing to a mountainous border region, taking 19 captured soldiers with them. They have demanded the release of Mr. Jomaa and several other Islamists jailed since a 2007 insurrection by a group inspired by Al Qaeda at a Palestinian refugee camp in northern Lebanon.
– The Islamic State has "distributed" about 300 Yazidi women to its jihadist fighters as spoils of war, CNN reports. The Islamic State, or ISIS, kidnapped the women when it attacked Yazidi villages and forced tens of thousands to flee earlier this month, according to a British group monitoring the crisis. The group says the Sunni extremists sold off at least 27 of the women to other ISIS members in Syria for $1,000 each. Some of the women converted to Islam for the marriages. In other ISIS news: John Kerry today called for a "world coalition" to defeat ISIS in a variety of ways: "To confront its nihilistic vision and genocidal agenda," the coalition would have to use "political, humanitarian, economic, law enforcement and intelligence tools to support military force," he wrote in a New York Times op-ed. ISIS militants beheaded a soldier in Lebanon and posted the beheading on social media, the New York Times reports. The soldier, also a Sunni, was captured when ISIS temporarily took over a Lebanese border town. ISIS is threatening to kill more captives if Lebanon doesn't release jihadist prisoners. Saudi Arabia's king warns that Islamist extremists are close to attacking Europe and the US. King Abdullah didn't mention ISIS by name, but his words "appeared aimed at drawing Washington and NATO forces into a wider fight" against the militant group, CBS News reports. Foreign Policy says it acquired an ISIS fighter's laptop that contains plans to create biological weapons, including one that spreads the bubonic plague. "The human casualties can be huge," said a 19-page instruction manual. But there was no evidence that ISIS already has such weapons. For more, read about an American woman being held by ISIS.
