Cameron 'convinced' UK should join IS airstrikes in Syria
David Cameron has said he is convinced that the UK should join airstrikes against Islamic State in Syria, following the attacks in Paris earlier this month.
Speaking in the French capital, he also visited the Bataclan concert hall - where 89 people were killed - with President Hollande.
The prime minister hopes to build a case to persuade MPs in Westminster to vote in favour of military action.
