BBC’s Gaza reporter kidnapped. Discuss!

Johnston has been the BBC's reporter in Gaza for three years

The BBC says it is concerned for the safety of a correspondent who has gone missing in the Gaza Strip.

The corporation said it had been unable to contact Alan Johnston, but did not comment on Palestinian reports that he had been kidnapped.

Johnston's car was found abandoned in Gaza City shortly after he left his office to drive home.

Several journalists and aid workers have recently been kidnapped in Gaza. All have been released unharmed.

Johnston has been the BBC's correspondent in the Gaza Strip for the past three years.

"We are currently unable to contact him and are concerned for his safety," the BBC said in a statement.

"We are trying to gather as much information as possible."

Details of what happened are sketchy. Palestinian police said four gunmen were seen in the vicinity of where Johnston's car was found.

Palestinian Interior Minister Sayeed Sayyam said Johnston's disappearance was a "criminal act".

Palestinian security forces have set up checkpoints around Gaza and are searching for the correspondent.
