Islamic State's key weakness lies in their "old-fashioned" manner of fighting, said the former director-general of a leading military thinktank.

Professor Michael Clarke,who previously headed up the Royal United Services Institute, spoke to Julia Hartley-Brewer as the battle for Mosul rages on.

A spokesman for the Iraqi forces revealed today that the soldiers have reached the outskirts of the city of Mosul and broken through Isis's front-lines forces, without any losses.

Professor Clarke said the jihadist group has a "clever" and"sophisticated psychological profile". But he said that when it comes down to physical fighting, they're remarkably old-fashioned because they use "light weapons" and other tactics that won't work against "a modern military force"
