More than 100 Muslim leaders from across the UK have signed an open letter calling for the release of British aid worker Alan Henning.

An expert on terrorism and Islam has said that those targeted in the overnight raids were likely motivated by what has been happening in Syria and Iraq rather than in Australia.
Greg Barton, acting director of the Centre for Islam and the Modern World at Monash University, described the raids in two Australian cities as "massive" and the "largest in history".
A British aid worker who was with Alan Henning when he was captured by Islamic State militants in Syria has pleaded for mercy for his friend.
In an interview with BBC News, Majid Freeman had this message for Mr Henning's captors:
He also spoke of Mr Henning's motivation in going to Syria:
Australian Prime Minister Tony Abbott has said that the overnight raids were prompted by fears that "demonstration killings" were being planned.
Speaking at a press conference, he said that police acted on intelligence showing directions from "an Australian who is apparently quite senior in ISIL ... to conduct demonstration killings here in this country".
"So this is not just suspicion, this is intent and that's why the police and security agencies decided to act in the way they have," he said.

Alexander Armstrong has landed the starring role for the return of much-loved cartoon character Danger Mouse.
The comedy actor - who hosts BBC One's Pointless - will be voicing the debonair but diminutive secret agent for his comeback next year, more than two decades after the series ended.

The new CBBC series will also feature the voice of Come Dine With Me, Dave Lamb, who has landed the all-important role of narrator.
Danger Mouse ended in 1992 and his return created a buzz when it was announced in June.
Scientists have overturned the widely-held view of chimpanzees and revealed that they are, like humans, natural-born killers.
A team of 30 researchers studied 152 killings by chimpanzees observed over five decades and concluded that the apes have an almost psychopathic tendency towards violence and slaughter.
A widely-held theory is that chimps only turn on each other when humans disrupt their forest habitats or food supplies.
Instead, the scientists found that human variables had no impact on the rates of killings and that the chimps fight and kill to get what they want and "eliminate rivals". The study is published in the journal Nature.
