At least 18 people were killed in shootings in central Paris late Friday, CNN affiliate BFMTV reported.
The network reported there was a hostage situation at one of the three sites where shootings took place. BFMTV said the ongoing hostage situation was at a theater named Bataclan.
There was a lockdown at the Stade de France due to possible explosions, according to French media. President Francois Hollande was at the stadium, watching France playing world champions Germany in a friendly soccer match, but he left to go to the Interior Ministry.
Police were outside the scene of one of the shootings, a restaurant in the 10th District.
