A taxi driver from near Manchester, England, Alan Henning was part of a team of volunteers that traveled to Syria in December 2013 to deliver food and water to people affected by the Middle Eastern country’s devastating civil war.
He was abducted the day after Christmas by masked gunmen, according to other people in the aid convoy.
Last week, the British Foreign Office released an audio file of Henning pleading for his life. His wife made a public plea for ISIS to spare his life.
Barbara Henning’s pleas were joined by voices of Muslim leaders around the world.
They included Shaykh Haitham Al Haddad, a judge on the Shariah Council in London, who has said that “whatever your grievance with American or British foreign policy, executing this man is not the answer.”
But the calls for mercy appear to have been met with bloodshed. If the authenticity of the video is confirmed, Henning will be the fourth Westerner to be beheaded on camera by ISIS.
This summer, ISIS beheaded American journalists James Foley and Steven Sotloff — gruesomely showing their killings in videos posted online. ISIS then claimed its first British victim, aid worker David Haines, according to video that appeared online on September 13.
Henning appeared kneeling in that last video, with an ISIS militant standing by his side.
