Andrew Mitchell said Thursday that Somalia poses a major threat, which may now be greater than the risks once posed by camps in Pakistan’s border regions.

Mitchell said “there are probably more British passport-holders engaged in terrorist training in Somalia than in any other country in the world.”

It follows warnings from the heads of Britain’s spy agencies about Britons training alongside Al-Shabab militants in Somalia.

Britain will host an international conference in February aimed at helping Somalia tackle militancy, piracy and its crippling humanitarian needs.
