Three people were killed and 13 others wounded, including a cameraman with Iraq's independent Al-Diyar satellite television, in a roadside bombing in Baghdad on Wednesday, officials said. Security official said the bomb exploded in the eastern neighbourhood of Talbiyah and killed three people. Thirteen people, including Al-Diyar cameraman Maytham Ibrahim, were wounded in the attack, the official said. Ibrahim survived but lost a leg, news editor Imed al-Abadi of the station was quoted as saying.He was walking down a street on his way to cover violence between Shiite militiamen and Iraqi and US forces that has ravaged parts of eastern Baghdad for more than a week when the attack occurred. Ibrahim is being treated in Imam Ali hospital in Sadr city, the sprawling bastion of the Mahdi Army militia of powerful Shiite cleric Moqtada al-Sadr that bore the brunt of violence this week. The station has asked for him to be transferred to a more sophisticated facility in Baghdad's heavily fortified Green Zone, Abadi said.The Paris-based media watchdog ‘Reporters Without Borders’, meanwhile, has called for the release of Ahmed Mahmud Hassan, a journalist for Al-Sumariya satellite television channel. It said Hassan was arrested on March 30 in Mahmudiyah, 30 kilometres south of Baghdad, "while covering clashes between Iraqi forces and rebel insurgents." The journalist is thought to be detained at a military base, Reporters Without Borders said."A score of journalists have been arrested across Iraq since the start of 2008," it said.
