Alan Henning charity campaigned for release of ‘Lady al-Qaeda’ Aafia Siddiqui

Alan Henning drove aid vehicles to Syria for the Aid4Syria charity

The British hostage Alan Henning was working for a charity that campaigned for the release of an al-Qaeda suspect whose freedom was demanded by his jihadi kidnappers, it has emerged.

Mr Henning was abducted while driving in a convoy organised by Aid4Syria, which has named a water project and emergency vehicles after Aafia Siddiqui, nicknamed “Lady al-Qaeda” in counterterrorism circles, who is currently serving an 86-year jail sentence in the US for attempted murder.

The Islamic State of Iraq and the Levant (ISIS), which has threatened to behead Mr Henning, demanded Siddiqui’s release in exchange for the life of his fellow hostage James Foley, who was murdered last month.

MI5, MI6 and Scotland Yard, which are investigating Mr Henning’s abduction and the murder of another British hostage, David Haines, are aware that Aid4Syria and ISIS share an interest in the release of Siddiqui, who tried to shoot two US soldiers after being arrested in Afghanistan with bomb-making instructions.

Simon Danczuk, MP for Rochdale, where Aid4Syria is based, said he had “concerns about what motives lie behind the work that is done by this organization”…
