Paris Attacks A 'Serious Cause For Concern'

Scotland Yard is to urgently review its tactics for responding to a Paris-style assault by terrorists in the aftermath of the attacks in the French capital. Metropolitan Police Commissioner Sir Bernard Hogan-Howe said the scale of the events in France and the weaponry used are a "serious cause for concern". The police presence at UK ports and major events are being stepped up in the wake of events across the Channel.
