BBC's Johnston says will be killed if captors stormed

A poster of the missing BBC journalist Alan Johnston, who disappeared in Gaza on March 12, is displayed during the World Economic Forum in the King Hussein Convention Centre at the Dead Sea May 18 2007. Hamas leader Ismail Haniyeh said on Sunday that the kidnappers of BBC correspondent Alan Johnston have made a new video of the abducted journalist wearing what appeared to be explosives around his waist.

DUBAI (Reuters) - BBC Gaza correspondent Alan Johnston appeared in a video posted on the Internet on Sunday wearing what he said was as an explosive belt which he said his captors will detonate if force was used to free him.

"The situation now is very serious as you can see I have been dressed in what is an explosive belt which the kidnappers say will be detonated if there was any attempt to storm this area," Johnston said in the video posted by the Army of Islam.

The Palestinian group has demanded Britain free Muslim prisoners, particularly the Islamist cleric Abu Qatada.
