Britain will take “whatever steps are necessary” to help an international push to destroy the “evil” extremist group who murdered aid worker David Haines, British Prime Minister David Cameron said today.
In an emotional statement in Downing Street after chairing a meeting of the Government’s Cobra emergency committee to discuss the killing, he hailed Mr Haines as a “British hero” and vowed to “hunt down those responsible and bring them to justice, no matter how long it takes”.
Islamic State (IS) were “not Muslims, they are monsters”, he said, and the UK could not afford to ignore the severe threat the jihadists’ spread posed to both world and domestic security.
The Islamic State released the footage showing the 44-year-old being murdered by a knife-wielding militant, who appears to speak with a British accent.
The clip also includes a threat to kill a second British hostage.
Mr Haines was captured in Syria in March last year. In a statement his brother said the father-of-two had been murdered “in cold blood”.
