Al Jazeera television today broadcast a video showing an appeal by three of four kidnapped peace activists being held hostage in Iraq.
The video bore a February 28th date stamp and showed the three men sitting in a room. They appeared in good health and were speaking to the camera, although their voices could not be heard.
Al Jazeera said the men had called on Gulf Arab leaders and their own governments to help free them.
A group calling itself the Swords of Truth kidnapped the men - two Canadians, one Briton and one American - in November. In January, the group said US-led forces had one last chance to free Iraqi prisoners or they would kill the men.
Briton Norman Kember, American Tom Fox and Canadians James Loney and Harmeet Sooden were kidnapped in Baghdad, where they were working with a Christian peace organisation.
It was not immediately clear which hostages were shown.
