The family of a Scottish aid worker thought to be being held by Islamic militants in Syria has urged his captors to contact them.
Islamic State (IS) extremists have threatened to kill David Haines and have not responded to any of the family's attempts to make contact so far, the Foreign and Commonwealth Office (FCO) said.
A statement on behalf of the family released by the FCO said: “We are the family of David Haines.
“We have sent messages to you to which we have not received a reply. We are asking those holding David to make contact with us.”
Mr Haines (44), was taken while working for ACTED in Syria in March 2013, having previously helped local people in Libya and South Sudan.
Militants from IS have beheaded two American journalists, posting the evidence online in gruesome videos featuring a masked jihadist with a British accent.
Mr Haines is seen kneeling in an orange jumpsuit, at the end of of video in which US journalist Steven Sotloff was killed.
British foreign secretary Philip Hammond has said the FCO will be doing “everything” they could to protect Mr Haines.
Mr Haines has a teenage daughter in Scotland from a previous marriage and a four-year-old daughter in Croatia from his present marriage.
Educated at Perth Academy secondary school, he has worked for aid agencies in some of the world’s worst trouble spots, including Libya and South Sudan.
He was in Libya during its civil war in 2011, working as head of mission for Handicap International, which helps disabled people in poverty and conflict zones around the world.
ACTED has previously said that the threats made to the Scotsman’s life were “intolerable”.
In a statement, it said: “ACTED strongly condemns the violence and threats against David. A man’s life should never be threatened on account of his humanitarian commitment.”
The charity said Mr Haines had worked as "a humanitarian" since 1999, helping people in the Balkans, the Middle East and Africa.
When he was taken by jihadists in Syria he was working to help “tens of thousands of people affected by the crisis” created by the long-running civil war.
