Britain's Cameron Says IS Planning Attacks 'In Britain'

British Prime Minister David Cameron has said militants from the Islamic State (IS) group are plotting "terrible acts in Britain and elsewhere."

In an interview with the BBC on June 29, Cameron added that, as long as IS exists, "we are at threat."

Cameron's remarks come days after an Islamist gunman killed dozens of tourists -- many of them Britons -- in Tunisia, an attack that British leaders have said is the worst assault on British citizens since the 2005 bombings in the London underground.
