Barbara Henning, the wife of British hostage Alan Henning, has urged his Islamic State captors to "please release him, we need him back home".
The 47-year-old aid worker was captured by militants in Syria last year and has been threatened with death by his Islamic State captors.
Video footage of British hostage Alan Henning filmed the day before his capture in Syria has been released in which he describes his trips to the country as "worthwhile".
The 47 year old was kidnapped while travelling with a humanitarian aid convoy shortly after crossing into Syria from Turkey.
"It's all worthwhile when you see what is needed, as you get where it needs to go. That makes it all worthwhile," Mr Henning says in the video, filmed on Christmas Day 2013.
"No sacrifice we do is nothing compared to what they are going through every day," he adds.
The oldest member of Alan Henning's family has demanded boots on the ground to combat Islamic State militants who killed their beloved Alan.
The wife of a British aid worker held by Islamic State militants has recorded a message to his captors appealing for his life to be spared.
