French President Francois Hollande and British Prime Minister David Cameron have visited the Bataclan concert venue in central Paris, which saw the worst carnage of the attacks that killed 130 people.

Hollande and Cameron were meeting Monday in Paris as the French leader presses for a stronger international coalition against Islamic State. He is headed to Washington and Moscow later in the week.

The decision to head to the Bataclan was not announced in advance and came amid tight security in both Paris and Brussels, home to many of the men identified as suspects in the Nov. 13 attack.
