A second British hostage facing execution by Islamic State (IS) militants has been identified as Alan Henning, a taxi driver from northwest England who was kidnapped during an aid mission to Syria.

Henning, 47, is understood to be from Eccles in Greater Manchester and a former taxi driver. He is believed to have been kidnapped around Christmas time last year, shortly after crossing the border from Turkey into Syria while traveling with a humanitarian aid convoy.

Henning volunteered to drive an ambulance full of medical aid to Syria with eight other volunteers from Bolton alongside the UK Arab Society. He helped load supplies, including defibrillators, stethoscopes and oxygen, into ambulances that were driven to Syria to help refugees.

In the footage, Henning was dressed in an orange jumpsuit. A masked militant standing next to him threatened to kill the hostage next if UK Prime Minister David Cameron continued to support the fight against the jihadist organization. The alleged executioner, speaking with a British accent, appears to be the same man shown in the previous two videos, in which American journalists James Foley and Steven Sotloff were beheaded.
