BANGKOK ? A fourth journalist has been shot and wounded while covering the latest clashes between the Thai army and anti-government protesters in Bangkok, one of his editors and a relative said.

Chaiwat Pumpuang, a photographer for The Nation newspaper, was shot in the leg and taken to hospital, said Veena Thoopkrajae, an editor at the Thai paper.

His brother told AFP that Chaiwat was in a serious condition after a bullet shattered a bone in his leg.

Two other Thai photographers were wounded in the leg Friday, while a Canadian cameraman for the France 24 news channel was gravely wounded the same day after being hit in the leg, torso and wrist by three bullets, his employer said.

The Canadian, Nelson Rand, was out of danger on Saturday, said a staffer at the hospital where he was being treated.

A Japanese cameraman was among 25 people killed on April 10 when clashes broke out during an attempt by troops to clear protesters from an area of the capital.

The New York-based Committee to Protect Journalists (CPJ), in a statement received Saturday, said it was "gravely concerned" about the deteriorating situation for journalists as government forces and protesters clashed.

Another media watchdog, Reporters Without Borders (RSF), called on the army and protesters "to guarantee the safety of the journalists" in the capital.

"The confusion reigning in various parts of Bangkok does not suffice to explain the shooting injuries sustained by several Thai and foreign journalists since April," it said in a statement.
