An employee at the printing business besieged by the Charlie Hebdo attackers was able to help police kill the terrorists after texting tactical information to them. 
 
 The 26-year-old graphic designer, who has been named in reports as Lilian Lepere, took refuge "under a sink in the canteen" upstairs at the business in Dammartin-en-Goele, according to Paris prosecutor Francois Molins. 
 
 Brothers Said and Cherif Kouachi were holed up there after killing 12 people at the offices of satirical magazine Charlie Hebdo and going on the run. 
 
 A source told the AFP news agency Mr Lepere was "terrified". 
 
 But despite this, he managed to remain undetected and began communicating with police outside via text message.

 Mr Lepere sent them "tactical elements such as his location inside the premises", Mr Molins said. 
 
 The source added that Mr Lepere could hear the suspects talking, which helped reassure him and gave him more information to send to the forces outside. 
 
 A separate source said the man was also able to communicate with his family. 
 
 The brothers had taken the manager of the store hostage, but released him after he helped Said with a neck wound he had sustained in a firefight with police.

 At around 5pm local time on Friday, automatic gunfire and explosions could be heard as police moved in to end the siege. 
 
 Officials said the brothers had emerged from the building and opened fire on police before they were killed. 
 
 An armoured car gave them access to the upper floor to free Mr Lepere, a source said. 
 
 He was taken to police headquarters, where he was quickly reunited with his family, another source close to the case said, adding he was "shocked" but "OK".

 Mr Lepere's father said the family was "doing fine", and thanked the police and the "people who helped". 
 
 At the same time, the siege at a kosher supermarket in Paris was also coming to a bloody end. 
 
 It began when Amedy Coulibaly, who is believed to be an ally of the brothers, went into the store and took out a Kalashnikov. 
 
 A father called Ilan and his three-year-old son quickly hid in the supermarket's refrigeration unit after Coulibaly burst in, two relatives told AFP.

 Sources close to the investigation said at least three other people were with them. 
 
 Ilan removed his jacket and wrapped his son in it to protect the toddler from the cold. 
 
 The group remained there for almost five hours. 
 
 Ilan's mother quickly realised her son and grandson were hidden and decided not to try and contact them.

 She instead gave her son's number to the police, who were able to use it to track the location of Ilan and other hostages inside the supermarket. 
 
 According to Mr Molins, this knowledge may have played a part in their survival when police finally stormed the store.

 The worst terrorist violence France has seen in decades killed at least 20 people, including the three gunmen. A fourth suspect — the common law wife of the market attacker — was still at large and believed to be armed. 
 
 Al-Qaida's branch in Yemen said it directed the attack against the publication Charlie Hebdo to avenge the honor of the Prophet Muhammad, a frequent target of the weekly's satire. 
 
 The brothers were not unknown to authorities: One had a terrorism-related conviction for ties to a network sending fighters to battle American forces in Iraq, and both were on the U.S. no-fly list, according to a U.S. official. 
 
 President Francois Hollande urged his nation to remain united and vigilant, and the city shut down a famed Jewish neighborhood amid fears of more violence. 
 
 "The threats facing France are not finished," Hollande said. "We are a free people who cave to no pressure." 
 
 The drama, which played out on live TV and social media, began with the brothers Said and Cherif Kouachi methodically massacring 12 people Wednesday at the Charlie Hebdo offices, stopping to shoot a wounded police officer in the head before escaping by car. 
 
 On Thursday, a gunman police identified as Amedy Coulibaly shot a policewoman to death south of Paris, although authorities were not sure at first if it was related to the Charlie Hebdo shootings. 
 
 It all ended at dusk Friday with near-simultaneous raids in two locations: a printing plant in the town of Dammartin-en-Goele, northeast of Paris, where the Kouachis were holed up, and the Paris supermarket where Coulibaly killed four hostages and threatened more violence unless the police let the Kouachis go. 
 
 As scores of black-clad security forces surrounded both sites, booming explosions, heavy gunfire and dense smoke heralded the news that the twin sieges finally had ended. 
 
 The three gunmen were dead — but the authorities also discovered four dead hostages at the market. Sixteen hostages were freed, one from the printing plant and 15 others from the store. 
 
 The attackers had ties both to each other and to terrorist activities that reached back years and extended from Paris to al-Qaida in Yemen. They epitomized Western authorities' greatest fear: Islamic radicals who trained abroad and came home to stage attacks. 
 
 After the killings at the Charlie Hebdo offices, Cherif Kouachi, 32, and his 34-year-old brother Said led police on a chase around northeastern France, robbing a gas station and stealing a car before ending up at the printing plant in Dammartin-en-Goele, near Charles de Gaulle airport. One of the brothers was wounded in the neck at one point during a shootout with police after he commandeered a car, Paris Prosecutor Francois Molins said. 
 
 Authorities said the brothers temporarily took a man hostage at the plant but let him go, and a second man was later discovered to have been hiding inside the building. 
 
 A member of the al-Qaida in the Arabian Peninsula gave a statement in English to The Associated Press saying the group's leadership "directed the operations and they have chosen their target carefully." 
 
 The attack was in line with warnings from the late al-Qaida leader Osama bin Laden to the West about "the consequences of the persistence in the blasphemy against Muslim sanctities," the member said, speaking on condition of anonymity because the group's regulations do not permit him to give his name. 
 
 The brothers were cornered there for much of the day before the explosions and gunfire rang out in the twilight and a police SWAT team clambered onto the roof. 
 
 "They said they want to die as martyrs," Yves Albarello, a local lawmaker inside the command post, told French television station i-Tele. 
 
 At the kosher grocery near the Porte de Vincennes neighborhood of the capital, the gunman burst in shooting just a few hours before the Jewish Sabbath began, declaring "You know who I am," the official recounted. 
 
 The attack came before sundown when the store would have been crowded with shoppers, and Hollande called it "a terrifying anti-Semitic act." 
 
 Coulibaly killed the four people in the market shortly after entering, Molins said. 
 
 Several people wounded in the grocery store were able to flee and get medical care, the official said. 
 
 About 100 students were locked down in nearby schools and the highway ringing Paris was closed. 
 
 The mayor's office also shut down all shops along Rosiers Street in the city's famed Marais neighborhood in the heart of the tourist district. Hours before the Jewish Sabbath, the street is usually crowded with shoppers. The street is also only a kilometer (half-mile) from Charlie Hebdo's offices. 
 
 Charles de Gaulle airport, not far from the standoff in Dammartin-en-Goele, briefly closed two runways to arrivals, and Hollande held a series of crisis meetings with his security team throughout the day. 
 
 Police released a photo of Coulibaly and his wife, Hayat Boumeddiene, described as an accomplice. 
 
 Authorities increasingly grew to see links between the attackers after they discovered that Boumeddiene and the companion of one of the Kouachi brothers had exchanged about 500 phone calls, Molins said. 
 
 He added that several people have been given preliminary charges in the investigation. They include relatives of the three gunmen. 
 
 Minutes before police stormed both sites, Coulibaly had threatened more violence if authorities launched an assault on the two brothers, a police official said. A group of people holed up in the supermarket's freezer — apparently unbeknownst to the gunman. 
 
 BFM also said it spoke with Coulibaly, who said he and the Kouachis were coordinating their actions, and that he was with the militant Islamic State group. The organizations are normally rivals. 
 
 The TV station said Coulibaly didn't hang up properly after the phone call and that this allowed police to hear him saying a final prayer before his death, perhaps suggesting that this prompted the police raid. 
 
 In the final assault, phalanxes of security forces converged on the store entrance behind a flash from a stun grenade — and fired inside. Frenzied civilians — one of them carrying a toddler — scurried out under escort by helmeted police in body armor. 
 
 Police said Coulibaly had been a co-suspect with Cherif Kouachi in a court case involving terrorism that never made it to trial. 
 
 Cherif Kouachi was convicted of terrorism charges in 2008 for ties to a network sending jihadis to fight U.S. forces in Iraq. 
 
 According to a Yemeni security official, Said Kouachi is suspected of having fought for al-Qaida in Yemen. Another senior security official added that Said was in Yemen until 2012. 
 
 Both officials spoke to the AP on condition of anonymity because of an ongoing investigation into Kouachi's stay in Yemen. 
 
 Both brothers were also on the U.S. no-fly list, a senior U.S. counterterrorism official said, speaking on condition of anonymity because the official was not authorized to discuss foreign intelligence publicly. 
 
 The attacks in France as well as a hostage siege last month in Sydney and the October killing of a solder near Canada's parliament prompted the U.S. State Department to issue a global travel warning for Americans. It also cites an increased risk of reprisals against U.S. and Western targets for the U.S.-led intervention against Islamic State militants in Syria and Iraq. 
 
 Authorities around Europe have warned of the threat posed by the return of Western jihadis trained in warfare. France counts at least 1,200 citizens in the war zone in Syria — headed there, returned or dead. Both the Islamic State group and al-Qaida have threatened France, home to Western Europe's largest Muslim population. 
 
 The publication Charlie Hebdo had long drawn threats for its depictions of Islam, although it also lampooned other religions and political figures. It had caricatured the Prophet Muhammad, and a sketch of Islamic State's leader was the last tweet sent by the irreverent newspaper minutes before the attack. 
 
 Eight journalists, two police officers, a maintenance worker and a visitor were killed in the newspaper attack, including the paper's editor. Charlie Hebdo plans a special edition next week, produced in the offices of another paper.

 The French government's work is not over. There's still a lot of healing to do, a lot of questions to answer about how to prevent future attacks, and the pursuit of a woman wanted in the policewoman's shooting.

 Charlie Hebdo attackers holed up in print shop 
 
 The day's drama began in Dammartin-en-Goele, where brothers Cherif and Said Kouachi ended up in a print shop in an industrial area. 
 
 A salesman, who identified himself only as Didier, told France Info radio that he shook one of the gunman's hands at about 8:30 a.m. as they arrived at the business. Didier said he first thought the man, who was dressed in black and heavily armed, was a police officer. 
 
 As he left, the armed man said, "Go, we don't kill civilians." Didier said, "It wasn't normal. I did not know what was going on."

 The gunmen told police that they wanted to die as martyrs, Yves Albarello, who is in France's Parliament, said on channel iTele. The area, meanwhile, was locked down -- with children stuck in schools, roads closed and shops shuttered. 
 
 Shortly before 5 p.m., gunshots and at least three large explosions pierced the relative silence. . 
 
 Soon after, men could be seen on the roof of the building where the brothers had holed up. Four helicopters landed nearby. 
 
 Word came that the brothers were dead and that a man who had been hiding in the building was safe, said Bernard Corneille, the mayor of nearby Othis. 
 
 Hostages at kosher grocery store 
 
 At the same time, in a different setting near Paris's Porte de Vincennes about 40 kilometers (25 miles) away, a similar crisis played out at a kosher store. 
 
 Amedy Coulibaly -- the same man who, authorities said, is suspected with Hayat Boumeddiene of killing a policewoman Thursday south of Paris -- on Friday took a number of hostages there. Boumeddiene remains at large. 
 
 Like Cherif Kouachi, a man claiming to be Coulibaly called BFMTV on Friday. At the scene, witnesses heard Coulibaly demand freedom for the Kouachi brothers, according to police union spokesman Pascal Disand.

 Law enforcement swarmed the area. Dozens of schools went on lockdown. 
 
 A resolution came a few minutes after the Dammartin-en-Goele climax, in the form of explosions and gunfire. Up to 20 heavily armed police officers moved into the store. They came out with a number of civilians. 
 
 Not everyone made it. Hollande said four people were killed. Israeli government sources told CNN that Hollande told Netanyahu that four hostages were killed and 15 were rescued. Molins said four hostages were killed by the gunman before police stormed the market. 
 
 Father: 'It's like a war' 
 
 In a speech Friday night, Hollande called the Porte de Vincennes deaths an "anti-Semitic" act. 
 
 He urged his countrymen not to respond with violence against Muslims, saying, "Those who committed these acts have nothing to do with the Muslim religion." 
 
 "Unity" he said, "is our best weapon." 
 
 Map: Standoffs near Paris, France 
 
 That kind of military language is apt when you're talking about two deadly attacks and violent standoffs in a few days. 
 
 It's something that a man, who asked to be called simply Teddy, understands. He was outside Henri Dunant elementary school in Dammartin-en-Goele on Friday, hoping to pick up his young son. 
 
 And, eventually, the students did leave the school -- accompanied by police officers who held their hands and, in some cases, lifted them onto an awaiting bus that would take them to safety. 
 
 "It's like a war," Teddy said. "I don't know how I will explain this to my 5-year-old son." 
 
 Parts of France on high alert 
 
 This "war" erupted two days ago, when a pair of heavily armed men -- hooded and dressed in black -- entered the Paris offices of Charlie Hebdo, the satirical magazine known for its provocative, often profane, take on religion, politics and most anything else. 
 
 They burst into a meeting, called out individuals, and then executed them. The dead included editor and cartoonist Stephane Charbonnier and four other well-known cartoonists known by the pen names: Cabu, Wolinski, Honore and Tignous.

 Authorities followed a lead Thursday morning from a gas station attendant near Villers-Cotterets, about 40 kilometers (25 miles) from Dammartin-en-Goele, whom Cherif Kouachi, 32, and Said Kouachi, 34, reportedly threatened as they stole food and gas. Police think the brothers may have later fled on foot into nearby woods. 
 
 Ties to Islamist extremists 
 
 As the suspects moved, the French government -- including more than 80,000 police deployed across the country -- also didn't stand still. 
 
 Some of them tried to prevent more bloodshed, which might have something to do with nine people detained after the Charlie Hebdo attacks. Investigators also dug to learn about the attackers. 
 
 Both men had ties to Islamist extremists. 
 
 Said Kouachi, left, and Cherif Kouachi are suspects in the Paris attack. 
 
 Said, the elder of the Kouachi brothers, spent several months in Yemen in 2011, receiving weapons training and working with al Qaeda in the Arabian Peninsula, according to U.S. officials. 
 
 His younger brother, Cherif, has a long history of jihad and anti-Semitism, according to documents obtained by CNN. In a 400-page court record, he is described as wanting to go to Iraq through Syria "to go and combat the Americans." 
 
 "I was ready to go and die in battle," he said in a deposition. "... I got this idea when I saw the injustices shown by television. ... I am speaking about the torture that the Americans have inflicted on the Iraqis." 
 
 Cherif was a close associate of Coulibaly, a Western intelligence source told CNN. 
 
 A man claiming to be Cherif told CNN affiliate BFMTV in a phone call before he was shot and killed Friday that he was sent to carry out the massacre by al Qaeda in Yemen and that the late Anwar al-Awlaki financed his trip. CNN cannot independently confirm the authenticity of the recording. 
 
 Al-Awlaki, an American-born Muslim scholar and cleric who acted as a spokesperson for al Qaeda in the Arabian Peninsula, was killed in 2011 by a CIA drone strike. 
 
 Cherif and Coulibaly were involved in a 2010 attempt to free an Algerian incarcerated for a 1995 subway bombing. Coulibaly was arrested with 240 rounds of ammunition for a Kalashnikov rifle and a photo of Djamel Beghal, a French Algerian once known as al Qaeda's premier European recruiter. 
 
 The Western intelligence source said that Coulibaly lived with Boumeddiene, his alleged accomplice in the police shooting, and that the two traveled to Malaysia together.

 A unity rally will be held Sunday "celebrating the values behind" Charlie Hebdo, said British Prime Minister David Cameron, who will travel to Paris to attend. 
 
 And the magazine itself -- whose former offices were firebombed in 2011, on the day it was to publish an issue poking fun at Islamic law and after it published a cartoon of the Muslim Prophet Mohammed -- will go on as well, even without its leader and most talented staffers. It's set to publish thousands of copies of its latest edition next Wednesday.

 Patrick Pelloux, a columnist for the magazine, told CNN that "I don't know if I'm afraid anymore, because I've seen fear. I was scared for my friends, and they are dead." 
 
 He and many others are defiant. 
 
 "I know that they didn't want us to be quiet," Pelloux said of the slain Charlie Hebdo staffers."They would be assassinated twice, if we remained silent."
– Some intriguing details about the role of cell phones in yesterday's dual raids in France that killed three suspected terrorists: Hidden helper: When Cherif and Said Kouachi holed up in a building outside Paris, they were unaware that a man identified as Lilian Lepere, 26, was hiding inside. He was reportedly under a sink but close enough to hear the brothers talk, and he began texting police information about their whereabouts, his whereabouts, and the building itself, reports Sky News. The dialogue lasted three hours, and a police official says it gave authorities crucial help ahead of the raid, reports the Wall Street Journal. Didn't hang up: The hostage-taker at the kosher market in Paris, Amedy Coulibaly, called a TV station at one point but failed to properly hang up the phone after talking. "This allowed police to hear him saying a final prayer before his death, perhaps suggesting that this prompted the police raid," reports AP. Hostage location: Several people at the market hid in a refrigeration unit, including a father and his toddler-age son. When the man's mother realized they were trapped inside the market, she opted not to call in case they were hidden. Instead, she gave the phone number to police, who were able to track the location of the hostages inside the store, reports AFP. The information may have helped them survive when the raid took place.
