UK must beef up its jihadi cyber defences, says ex-CIA chief

Former CIA director General David Petraeus yesterday warned Britain must beef up its cyber defences to stop extremists acquiring virtual weapons of mass destruction.

The ex-intelligence chief, one of the most senior post-9/11 US military commanders, said one day soon there would be a ‘stake through the heart’ of Islamic State’s leader.

But he warned the West could not just play ‘whack a mole’ when it came to defeating the group online, as he slapped down web giants for not doing enough to stop terror.
