An international rights group called on Bahrain to stop harassment and intimidation of reporters critical of the government, which crushed weeks of protests earlier this year.
The US-based Committee to Protect Journalists (CPJ) said in a statement released late on Tuesday that it had documented cases of two journalists dying in custody and many others being detained or assaulted in the kingdom.
"Bahrain's government has a responsibility to protect journalists from those who resort to threats of violence, intimidation, or fabricated criminal charges to influence coverage," said Mohamed Abdel Dayem, CPJ's regional programme coordinator.
Despite a national dialogue launched in July, small protests have erupted daily in villages near the capital.
On Sunday, a local journalist was summoned by public prosecutors over accusations that she hit a woman who had joined pro-government supporters in breaking up a news conference held by an Irish delegation investigating rights abuses against medics.
