Muslim groups across Britain united on Saturday to join Prime Minister David Cameron in condemning the beheading of aid worker Alan Henning by Islamic State insurgents.
Prayers for the 47-year-old taxi driver were said in mosques throughout Britain at the start of the Muslim Eid al-Adha festival, as his family said they were numb with grief.
Cameron called Henning a gentle, compassionate man who had simply tried to help others, and said Britain would do all it could to destroy his killers.
