PARIS (AP) — French President Francois Hollande vowed to attack the Islamic State group without mercy as the jihadist group claimed responsibility Saturday for orchestrating the deadliest attacks on France since World War II.
Hollande said at least 127 people died Friday night when attackers launched gun attacks at Paris cafes, detonated suicide bombs near France's national stadium and killed hostages inside a concert hall during a rock show. More than 200 people were injured, dozens critically.
Hollande, who declared three days of national mourning and raised the nation's security to its highest level, called the carnage "an act of war that was prepared, organized, planned from abroad with internal help."
The Islamic State group's claim of responsibility appeared in Arabic and French in an online statement circulated by IS supporters. It was not immediately possible to confirm the authenticity of the admission, which bore the group's logo and resembled previous verified statements from the group. The statement mocked France's involvement in air attacks on suspected IS bases in Syria and Iraq, noting that France's air power was "of no use to them in the streets and rotten alleys of Paris."
Many of the city's top tourist attractions closed Saturday, including the Eiffel Tower, the Louvre Museum and the Disneyland theme park east of the capital.
Parisians expressed shock, disgust and defiance in equal measure. Some areas were quiet, but hundreds queued outside a hospital near the Bataclan concert hall, scene of the worst violence, to donate blood. As a shrine of flowers expanded along the sidewalk, a lone guitarist sang John Lennon's peace ballad, "Imagine."
Ahsan Naeem, who has lived in Paris for the past seven years, said he and his friends — one of whom was hurt by "bullet shrapnel" inside the club — were still in shock.
"These places are the places we visit every week," he said. "Streets we walk every day. I've seen dozens of gigs at the Bataclan. Eaten at the Petit Cambodge. Sat outside Le Carillon on so many nights."
Authorities said eight attackers died, seven in suicide bombings, a new terror tactic in France. Police said they shot and killed the other assailant.
Officials said a suicide bomber at the concert hall was identified as a young Frenchman flagged in the past for links with an Islamic extremist activity, and a Syrian passport was recovered from the remains of another suicide bomber outside the stadium.
Officials in Greece said the attacker with the Syrian passport had entered in October through Leros, one of the islands that tens of thousands of people fleeing war and poverty in Syria and elsewhere have been using as a gateway to the the European Union in recent months.
French anti-terror police worked to identify potential accomplices to the attackers, and prosecutor's office spokeswoman Agnes Thibault-Lecuivre said authorities couldn't rule out the possibility that other militants involved in the attack remained at large.
The violence raised questions about security for the millions of tourists who come to Paris and for world events routinely hosted in the normally luminous capital, where 1,500 troops were deployed to support police in restoring order and reassuring a frightened populace.
French Interior Minister Bernard Cazeneuve announced that all public demonstrations would be banned until Thursday and local governments would have the option to impose nightly curfews. He said police and military reinforcements would be deployed to key public buildings.
The attacks, on an unusually balmy November Friday evening, struck at the heart of Parisian life: diners in cafes, concertgoers watching a rock band, spectators at a soccer match.
Paris Mayor Anne Hidalgo said the places attacked are ones Parisians love, where they celebrate diversity.
"It is this Paris that was hit, probably because this example of living together, which is so strong in our city, is unbearable for fanatical people," she said.
Hollande said the attacks meant France would increase its military efforts to crush IS. He said France — which besides bombing suspected IS targets in Syria and Iraq as part of the U.S.-led coalition also has troops fighting militants in Africa — "will be merciless toward the barbarians of Islamic State group."
Reflecting fears in other European capitals of the risk of coordinated or copycat attacks, the British government mounted a meeting of its emergency committee, known as COBRA. Italy said it was raising security levels on borders and major public places.
British Prime Minister David Cameron's office said "a small number of British nationals have been caught up in the attack."
The militants launched at least six gun and bomb attacks in rapid succession on apparently indiscriminate civilian targets Friday night.
Three suicide bombs targeted spots around the national Stade de France stadium, in the north of the capital, where Hollande was watching a France-Germany soccer match. Fans inside the stadium recoiled at the sound of explosions, but the match continued.
Around the same time, fusillades of bullets shattered the clinking of wine glasses in a trendy Paris neighborhood as gunmen targeted a string of crowded cafes. At least 37 people were killed, according to Paris Prosecutor Francois Molins.
The attackers next stormed the Bataclan concert hall, which was hosting the American rock band Eagles of Death Metal. They opened fire on the panicked audience and took members hostage. As police closed in, three detonated explosive belts, killing themselves, according to Paris police chief Michel Cadot.
Another attacker detonated a suicide bomb on Boulevard Voltaire, near the music hall, the prosecutor's office said.
Video shot from an apartment balcony and posted by newspaper Le Monde Saturday captured some of that horror as dozens of people fled from gunfire outside the Bataclan down a passageway to a side street.
At least one person lies writhing on the ground as scores more stream past, some bloodied or limping. The camera pans down the street to reveal more fleeing people dragging two bodies along the ground. A woman and two others can be seen clinging to upper-floor balcony railings in an apparent desperate bid to stay out of the line of fire.
Le Monde said its reporter Daniel Psenney filed the scene from his apartment balcony, and was shot in the arm when he went downstairs to help someone who had collapsed in the alley.
A tall, sturdy 38-year-old concert-goer named Sylvain collapsed in tears as he recounted the attack, the chaos and his escape during a lull in gunfire.
"First I heard explosions, and I thought it was firecrackers," he said.
"Very soon I smelled powder, and I understood what was happening. There were shots everywhere, in waves. I lay down on the floor. I saw at least two shooters, but I heard others talk. They cried, 'It's Hollande's fault.' I heard one of the shooters shout, 'Allahu Akbar,'" Sylvain told The Associated Press. He spoke on condition that his full name not be used out of concern for his safety.
The Paris carnage was the worst in a series of attacks claimed by the Islamic State in the past three days. On Thursday, twin suicide bombings in Beirut killed at least 43 people and wounded more than 200, and 26 people died Friday in Baghdad in a suicide blast and a roadside bombing that targeted Shiites.
The militant group also suffered significant reversals this week, with Kurdish forces launching an offensive to retake the strategic Iraqi city of Sinjar and the U.S. military saying it had likely killed Mohammed Emwazi, the masked British-accented militant known as "Jihadi John" who is seen in grisly IS beheading videos.
Jihadis on Twitter immediately praised the attackers and criticized France's military operations against Islamic State extremists.
Hollande declared a state of emergency, announced renewed border checks along frontiers that are normally open under Europe's free-travel zone, and canceled a planned trip to this weekend's G-20 summit in Turkey.
France has been on edge since January, when Islamic extremists attacked the satirical newspaper Charlie Hebdo, which had run cartoons of the Prophet Muhammad, and a kosher grocery. Twenty people died in those attacks, including three shooters.
French authorities are particularly concerned about the threat from hundreds of French Islamic radicals who have traveled to Syria and returned home with skills to mount attacks.
"The big question on everyone's mind is: Were these attackers — if they turn out to be connected to one of the groups in Syria — were they homegrown terrorists or were they returning fighters?" said Brian Michael Jenkins, a terrorism expert and senior adviser to the president of the Washington-based RAND Corporation.
