US President Barack Obama has visited the scene of the Bataclan theatre attack in Paris, after arriving in the city for the UN climate change summit.
Accompanied by French President Francois Hollande and Paris Mayor Anne Hidalgo, he laid a single white rose at the venue where 90 people were killed.
Security was stepped up for the visit, with helicopters flying overhead and roads in the area sealed off.
About 150 world leaders are attending the summit which opens on Monday.
Mr Obama's motorcade went straight to the Bataclan shortly after the US president arrived at Orly Airport.
After placing his rose, Mr. Obama stood in silence with his head bowed and his hands clasped in front of him. He then walked away with his arms around Mr. Hollande and Ms. Hidalgo.
