From the BBC:

The alleged kidnappers of BBC Gaza correspondent Alan Johnston have denied that they have reached a deal announced by Hamas for his imminent release.

In a video shown on al-Jazeera TV, a masked man said to be from the Army of Islam said there were "developments" in meetings with Hamas.

But he maintained that the reporter could still be killed if their demands were not met.

The BBC said it was aware of the video and was watching developments closely.
