Tunisia attack: David Cameron says 'we will beat terror threat'

Prime Minister David Cameron has promised a "full spectrum response" to Islamist extremism, after at least 30 British tourists were killed in Friday's attack on a Tunisian beach resort.

Speaking to BBC Radio 4's Today programme, Mr Cameron said the killings were ''absolutely horrific'' - but the terror threat would be beaten.

''This is, I think, going to be the struggle of our generation - and we have to fight it with everything we can,'' he said.
