British Prime Minister David Cameron and French President Francois Hollande laid a wreath at the Bataclan concert hall in Paris on Monday where 90 people were killed by extremist attackers.

Cameron said on his Twitter account he had stood "shoulder to shoulder" with Hollande at the venue, where a British man was among the dead on November 13.

The two leaders went on to have talks at the Elysee Palace at which Hollande was expected to tell Cameron of his plans for an international coalition to crush the so-called Islamic State in Iraq and Levant (ISIL) after the Takfiri group claimed responsibility for the Paris carnage.

Cameron is believed to be pushing to secure parliamentary support for a possible motion to launch British air strikes on IS targets in Syria.

In an article in the Daily Telegraph on Monday, he wrote that the Paris attacks showed that ISIL "is not some remote problem thousands of miles away; it is a direct threat to our security".
