British Prime Minister, David Cameron, on Saturday condemned what he described as barbaric murder of British hostage, Alan Henning by Islamic State (IS) terrorist group and vowed to hunt them down.
Cameron spoke after receiving security report from British Foreign Office at his rural retreat in Chequers.
The IS had on Friday released footage showing the beheading of Henning, a 47-year-old aid convoy volunteer, who was the fourth western captive it had killed.
Report said that Henning was a Manchester taxi driver who traveled to Syria to help distribute food and clothing to stricken civilians.
“What we must do with our allies is everything we can to defeat this organisation in the region, but also to defeat it at home.
“We must do everything we can to hunt down and find the people responsible for this.
“His killers will be hunted down and face justice,’’ Cameron said
The IS had previously released videos showing the beheading of two U.S journalists, James Foley and Steven Sotloff, as well as British aid worker, David Haines.
