The ruthless Islamic terrorist behind the kidnapping of hundreds of Nigerian schoolgirls is believed to be holed up in abandoned military bunkers deep inside a remote forest eight times larger than Yellowstone and teeming with "wicked and poisonous" snakes. 
 
 The dreaded Sambisa Forest, a game reserve in the northeastern part of the embattled nation, provides bloodthirsty Boko Haram leader Abubakar Shekau safe haven from Nigeria's security forces, many of whom are said to be afraid to venture into the wooded no man's land. The shadowy leader, his army of jihadist fighters and 276 teenage girls he vowed to sell into slavery or as child brides are believed to have melted into rugged wilderness. The girls are to be sold for as little as $12, according to reports. 
 
 The Nigerian government has reached out to the United States for help in hunting down the terrorists and has offered a $300,000 reward for information leading to Shekau's capture. But catching the continent's most-wanted man will require venturing into the 23,000-square-mile Sambisa, whose dangers have taken on mythical proportions. With confidence in Nigerian authorities completely eroded, local residents have reportedly pooled money for motorcycles to head into the forest in search of the girls missing since last month’s abduction, as well those who have been abducted since. At least two of the girls have died of snakebites, and roughly 20 others are believed to be ill, according to an intermediary. 
 
 Shekau made his evil plans clear in a video released Monday, in which he gloated about the kidnappings. 
 
 "I abducted your girls," Shekau said, in an hour-long video that opens with fighters shooting guns into the air and shouting "Allahu akbar!" "By Allah, I will sell them in the marketplace.” 
 
 Shekau's army is estimated to number from a few hundred to a few thousand fighters. The U.S. has offered to send a team to Nigeria to help the search efforts. A senior federal law enforcement source told Fox News that although the FBI has a permanent presence in Lagos, Nigeria, it’s "still unclear, what, if any” supplemental resources are being provided by the FBI. The FBI's elite Hostage Rescue Team is not in play at this time, the source said. 
 
 The forest's thorny vegetation is 6 feet high in some places, impenetrable without the use of heavy cutlasses to chop trails. According to locals, the wilderness was a primary grazing grounds for stray elephants from central Africa as a game reserve before 2006. It’s now believed that Boko Haram could be hiding in bunkers here previously used by the military to protect the indigenous residents of the region. 
 
 In recent days, Boko Haram has raided villages in and around the forest, including a raid Monday night on a village near the border with Chad, in which eight more girls were kidnapped. 
 
 Umar Maryah, a professor at Nigeria’s University of Maiduguri, told The Guardian that the forest hosts a large population of wildlife, including giant crustaceans, monkeys, antelopes, lions, elephants and ostriches. 
 
 Boko Haram militants are reportedly well-versed on the enormous forest and would likely see any military approach long in advance. 
 
 “It actually took the intelligence services a long time to discover that the game reserve had become a hideout for the sect,” one source told The Nation. “They waited three years until several lives had been lost before acting reluctantly on the intelligence advises … As a matter of fact, Sambisa is not the only hideout of the insurgents.” 
 
 The young hostages will be tactically transported from one base to another, typically during the cover of nightfall, to avoid detection, the source added. 
 
 Meanwhile, little is known about the group’s notoriously vicious leader. Shekau -- who is believed to be as young as 36 or as old as 45 -- was reportedly Boko Haram’s deputy leader until its founder, Mohammed Yusuf, was killed in a massive crackdown by local authorities in 2009. Shekau was initially thought to have also been killed during those attacks, but he later surfaced in a video claiming to be the terror group’s new director. 
 
 The U.S. Department of State is offering a reward of up to $7 million for information leading to Shekau’s location. In 2012, he was declared as a “specially designated global terrorist” for numerous bombings, including the August 2011 attack on the UN office complex in Nigeria’s capital, Abuja, that killed 23 people and injured dozens more. 
 
 Shekau, according to a BBC profile, is known as a “fearless loner” with a photographic memory, a complex and often paradoxical man whom is part intellectual, part terrorist. His nickname — Darul Tawheed — translates as a specialist in Tawheed, or the concept of monotheism in Islam. 
 
 “He hardly talks,” one journalist, Ahmed Salkida, told BBC. “He is fearless … He is one of those who believes that you can sacrifice anything for your belief.” 
 
 Shekau does not speak English, but is fluent in his native Kanuri, Hausa and Arabic languages. He reportedly does not even communicate directly with the group’s soldiers. 
 
 “A lot of those calling themselves leaders in the group do not even have contact with him,” Salkida told BBC. 
 
 Shekau, according to those who study the group, is known for being particularly brutal. 
 
 “I enjoy killing anyone that God commands me to kill — the way I enjoy killing chickens and rams,” he said in a clip released in 2012 after an attack in Kano, Nigeria, that killed more than 180 people. 
 
 In addition to being the group’s militant leader, Shekau also serves as its spiritual leader, Salkida said. 
 
 “He has a photographic memory and is well versed in theology,” he told BBC. 
 
 Meanwhile, on Wednesday, as many as 300 people were killed when extremists attacked the town of Gamboru Ngala on Nigeria's border with Cameroon, according to local reports. The attack and hundreds of casualties were confirmed Wednesday by Borno state information commissioner Mohammed Bulama who spoke to The Associated Press by telephone Wednesday. Shops and homes were set ablaze and razed in the attack, he said. 
 
 Nigerian federal Senator Ahmed Zannah said the attack lasted about 12 hours, according to the newspaper. The insurgents set homes on fire and gunned down residents who tried to escape from the flames. Zannah blamed fighters of Nigeria's homegrown Boko Haram terrorist network that has claimed responsibility for the kidnapping of 276 teenage girls and is threatening to sell them into slavery. 
 
 Boko Haram's five-year-old Islamic uprising has claimed the lives of thousands of Muslims and Christians. More than 1,500 people have died in their attacks so far this year. The insurgents say Western influences are corrupting and they want to impose an Islamic state in Nigeria, a country of 170 million where half the population is Christian, The Associated Press reports. ||||| One of the school students snatched by Boko Haram when they raided a Nigerian dormitory has been found wandering through a small north-eastern village, the first confirmed escape since the atrocity that shocked the world in April this year. 
 
 Of the almost 300 girls and young women rounded up and carted away after Boko Haram stormed Chibok secondary school, a handful fled during the initial confusion. A relentless string of attacks in remote northern towns in Boko Haram’s stronghold of Borno state prompted a summit in Paris that led to a renewed military push from Nigeria, neighbours Chad, Cameroon and Niger, and western allies including the US and the UK. But five months on, 276 of the girls remain in captivity and abductions continue to be used as a strategy by the extremists. 
 
 Conflicting details emerged about how the 20-year-old was found, with officials saying she was dropped off by suspected militants, while residents said she had escaped. 
 
 The police spokesman Emmanuel Ojukwu said: “I can confirm that on 24 September 2014 at about 5pm, a girl, 20 years of age, among the abducted Chibok girls was dropped off by suspected Boko Haram militants at Mubi in Adamawa state. Her condition is stable. She is getting the best of medical attention. The information we have is that she is one of the abducted girls. Other details will be made known to you in due course.” 
 
 Locals said she was found wandering through fields on the outskirts of Hong, a district in Adamawa, which neighbours Borno state. “Nobody knows how she came here. She was either released or escaped. She had been running around the bush for about four days before she reached here,” said Musa Sule, a local farmer. Locals and officials said a Boko Haram cell is known to be located in Damboa, more than 75 miles (120km) away. The sect was previously headquartered in the sprawling Sambisa forest, near Damboa, and continues to use it as a base and training camp. 
 
 The first confirmation of an escape comes after the Nigerian army earlier this week said dozens of girls had been released and were being looked after in an army barracks. They later retracted the statement and said none of the teenagers had been freed. 
 
 The young woman was visited by a member of the “Abuja Family”, a small group of relatives and supporters who hold daily rallies in the capital, Abuja. The member told the Guardian the young woman was in a state of extreme trauma and was unable to talk about what he called her “torture”. 
 
 “Right now she’s not in a position to explain exactly how she escaped. All we know is she either fled or was released by the group because they felt she had become a burden,” he said. 
 
 The escape could potentially shed light on where the other girls and young women still in captivity are being held. Boko Haram is in talks with the Nigerian government to secure a hostage-swap deal for dozens of their senior commanders currently in prison, although all previous negotiations have foundered. 
 
 As a group of parents gathered in Abuja to hold their daily vigil, most were torn between joy and despair. “We are all happy that one of our girls has escaped,” another father said, speaking on condition of anonymity as all the group members have agreed to do. “But it is difficult seeing the state the girl was in, and to think about what is happening to the others. We cannot be truly be happy until all our girls are brought home.” 
 
 Previous escapees interviewed by the Guardian spoke of multiple rapes, mutilations and forcible conversions. Several entered a catatonic trance at the mention of the sect’s name.
– Boko Haram has a tactical advantage: The Muslim extremist group suspected of kidnapping Nigerian girls is hiding out in old military bunkers, in an enormous forest where vegetation grows as high as six feet, Fox News reports. What's more, the 23,000-square-mile Sambisa Forest is teeming with poisonous snakes (two girls have apparently died of snakebites, and 20 are ill) and hosts varied wildlife including monkeys, antelopes, and lions, reports the Guardian. The wilderness was once a grazing grounds for elephants, whose thick skin could tolerate the thorny vegetation—but without cutlasses, it can be impenetrable to human visitors. "It actually took the intelligence services a long time to discover that the game reserve had become a hideout for the sect," a source tells the Nation. Only after three years and the loss of "several lives" did services come around, but now agents "are not ready to risk their lives any more after all the frustration." National police offered a $300,000 reward today for information leading to the girls' rescue, and the US has sent a team to help, but the Guardian notes that even the use of tanks wouldn't give authorities a clear tactical advantage. Meanwhile, Boko Haram is said to be moving the girls at night, possibly to a second base outside the forest.
