The Committee to Protect Journalists (CJP) has called on Hamas authorities in Gaza to allow three Palestinian newspapers to circulate freely in the territory.
The pro-Fatah West Bank newspapers - Al-Hayat al-Jadida, Al-Ayyam, and Al-Quds - say their staff were not allowed entry to Gaza unless they agreed to sign a document stating they would not criticise the government.
The CPJ's deputy director Robert Mahoney said: "To demand that newspapers agree not to criticise the government is an unacceptable form of censorship."
