The family of a British aid worker murdered by Islamic extremists have paid tribute to him, saying he was a humanitarian who was killed in cold blood.
Video of footage of the murder of David Haines, 44, by Islamic State militants emerged overnight.
He was taken hostage while working for ACTED in Syria in March last year.
In a statement issued by the Foreign Office, his brother Mike Haines said: “David was most alive and enthusiastic in his humanitarian roles.
"His joy and anticipation for the work he went to do in Syria is for myself and family the most important element of this whole sad affair.
"He was and is loved by all his family and will be missed terribly."
Earlier, the Prime Minister David Cameron described the beheading of the aid worker as ?an act of pure evil? after Islamic State released graphic footage of it.
