Three more journalists working in Iraq, a correspondent for al-Arabiya TV, her engineer and a cameraman, were shot and killed while reporting from Samarra Saturday, bringing to 82 the number of journalists and other news personnel who have died covering the war since it began nearly three years ago, according to the international organization Reporters Sans Frontières. In the 20 years of fighting in Vietnam from 1955-1975, 66 journalists were killed. The correspondent, Atwar Bahjat, was the seventh female journalist to die in Iraq. She and her crew were killed by unidentified gunmen as they covered the destruction of the Golden Mosque.
