A media watchdog group has called on Palestinian President Mahmoud Abbas to do more to secure the release of the BBC's kidnapped Gaza correspondent.
Alan Johnston has been held captive for more than month
Alan Johnston, 44, has not been seen since he was seized at gunpoint on his way home in Gaza City on 12 March.
Reporters Without Borders called on Mr Abbas to urge the kidnappers to provide evidence Mr Johnston is still alive.
Mr Abbas has said Mr Johnston is alive and that his government is working with the British authorities on the case.
Mr Abbas said again on Friday that Mr Johnston was alive but that he could not provide more details in order to protect the reporter's security.
On Thursday, Mr Abbas said he knew which group was holding Mr Johnston but he would not say whether any contact had been made with the captors.
An unknown militant group said on Sunday that it had killed him, but both the BBC and Palestinian officials have said they have been unable to verify the claim.
Protests against Mr Johnston's kidnap have been held in Britain, the Palestinian territories and other parts of the Middle East almost daily since his abduction.
