While there are few details in the public domain, it is understood that Alan Henning's family has received an audio file of him "pleading for his life" at the hands of his Islamic State captors.
Following a statement at the weekend from Alan's wife, urging IS to open a dialogue about his release, another statement has been issued through the Foreign Office...
"I and people representing me continue to reach out to those holding Alan. Islamic State continue to ignore our pleas to open dialogue. I have seen Muslims across the globe question Islamic State over Alan's fate. The voices of the people have spoken out loud and clear.
"He was working with Muslims to help the most vulnerable within Syria. Nothing has changed. He went to Syria to help his Muslim friends deliver much needed aid. We are at a loss why those leading Islamic State cannot open their hearts and minds to the facts surrounding Alan's imprisonment and why they continue to threaten his life.
"I have been told that he has been to a Sharia court and found innocent of being a spy and declared to be no threat. I implore Islamic State to abide by the decisions of their own justice system.
"Please release Alan."
