(Yahoo!News) Islamist militants in Syria are planning “mass casualty attacks” on Western targets, the head of British spy agency MI5 has warned, saying the deadly shooting in Paris was only a reminder of an ongoing threat.
Security Service chief Andrew Parker was referring in particular to a group of fighters known as Khorasan, sources said, who have been targeted by US warplanes in strikes in northwest Syria.
He warned that intelligence agencies needed more powers, in particular to intercept communications, but added: “Although we and our partners try our utmost, we know that we cannot hope to stop everything.”
