MPs have overwhelmingly backed UK air strikes against so-called Islamic State in Syria, by 397 votes to 223, after an impassioned 10-hour Commons debate.
A total of 66 Labour MPs sided with the government as David Cameron secured a larger than expected Commons majority.
The PM said they had "taken the right decision to keep the country safe".
Labour leader Jeremy Corbyn had said the case for war did "not stack up" but shadow foreign secretary Hilary Benn had urged MPs to "confront this evil".
