Alan Johnston has been held since 12 March |
The kidnappers of BBC correspondent Alan Johnston have renewed their threat to kill him if their demands for Muslim prisoners to be freed are not met.
The message comes a day after a video was released in which Mr Johnston wore what he said was an explosives belt.
In the tape, the reporter said his captors had promised to detonate it if force was used to try to free him.
Mr Johnston was abducted in Gaza on 12 March by the previously unknown radical Islamist group, The Army of Islam.
"The demands are very clear," Tuesday's statement from the militants said - listing the names of prisoners it wants released.
They include Abu Qatada, a Palestinian-born Islamic cleric who is suspected of having close links with al-Qaeda and is held by the UK government as a threat to national security.
"There is no discussion or bargaining in this issue," the statement said.
