London, November 17 (RHC)-- British Prime Minister David Cameron has unveiled London’s plans to hire some 1,900 more spies in a bid to counter terror threats against the country. "Our security and intelligence services have stopped something like seven attacks in the last six months albeit attacks planned on a smaller scale. That's one of the reasons we are strengthening the security and intelligence services," Cameron said on Monday.

The boost will see the total number of spying staff at MI5, MI6 and GCHQ increase from nearly 12,700 to 14,600 or by 15%. Cameron also said the British government plans to more than double spending on aviation security which already costs 9 million pounds a year.

The “step change,” which will take effect within five years, comes in the wake of the crash of a Russian airliner over Sinai in Egypt last month which claimed 224 lives.

The ISIL terrorist group has claimed responsibility for the deadly attack and Russia has confirmed that the plane was brought down by an explosive device planted on board.
