About 140 people were killed Friday in 7 separate attacks — shootings and explosions among them— around Paris, police and news outlets said.
A police official said 11 people were killed in a Paris restaurant in the 10th arrondissement, and others said at least twice that number died elsewhere, primarily in the Bataclan concert hall, where the hostages were taken. It was unclear how many people were in the hall; one official said there were around 100 while another said there were far fewer.
Hollande later announced that he would not participate in the G20 meeting in Turkey this weekend. The official Twitter account of the French presidency tweeted that Hollande would bring together a council of defense meeting Saturday morning at 9 local time.

U.S. Secretary of State John Kerry said Friday evening that the American embassy in Paris is making every effort to account for U.S. citizens after the attacks.
German Chancellor Angela Merkel said Friday evening that she was deeply distressed by the news and images from Paris, and that her thoughts were with the victims.
Other European officials were quick to comment on the incident, with European Council President Donald Tusk tweeting that he was shocked by the attacks, and he offers his "full solidarity & sympathy with the French people and authorities."
