President Barack Obama paid a late-night tribute to those killed in the terrorist attacks in Paris as soon as he arrived for climate talks in the French capital.
The US president’s motorcade went straight from Orly Airport to the Bataclan concert hall, one of the sites the terrorists struck on November 13.
French president Francois Hollande and the mayor of Paris, Anne Hidalgo, joined Mr Obama.
Each placed a single flower at a makeshift memorial and Mr Obama bowed his head in silence.
Some 130 people died in the deadliest attack on French soil in more than a half-century. The Islamic State group claimed responsibility.
Mr Obama flew to Paris for the opening two days of an international conference on combating climate change.
