David Cameron says seven attacks prevented in UK

Security services have prevented seven attacks in the last six months, British prime minister David Cameron said as he warned a Paris-style attack “could happen here” and announced he will boost intelligence agency staff by 15%, an extra 1,900 officers.

Cameron said the terror spree in France “was the sort of thing we warned about” in planning with the security services but such atrocities meant “you have to go right back to the drawing board” to work out what more steps needed to be taken, he said.

Asked if his country was at war with IS, he said Britainstands in “total solidarity” with France and would do “everything we can” to defeat the jihadis.
