Prayers are being offered in churches and mosques for Alan Henning, a British aid worker murdered by Islamic State militants, as another Briton is reunited with his family after being freed by captors in Libya.

A church in Henning's home town of Eccles, northwest England, was holding a multi-faith service of "reflection and solidarity" in his memory Sunday.

Muslim leaders also urged worshippers to pray for the taxi driver, captured while delivering aid to Syria, as they gather this weekend to celebrate the Eid al-Adha holiday.

A video purportedly showing Henning's beheading was released by militants Friday.

On Saturday, the British government announced the release of David Bolam, a teacher at the Benghazi European School. He was captured four months ago by a group calling itself the Army of Islam.
