Unknown gunmen opened fire on a funeral procession Saturday in a Sunni neighborhood of Beirut earlier seized by Shi'ite gunmen, killing two and wounding two, police said. The shooting at Tarik Jadideh underlined the state of lawlessness that has engulfed the Lebanese capital's Muslim sector since sectarian fighting erupted on Wednesday resulting in Hizbullah's takeover of neighborhoods from Sunnis loyal to the US-backed government. An Associated Press photographer who witnessed the shooting said the attack came as a procession of 200 people headed toward a nearby cemetery to bury a 24-year-old killed in this week's fighting. Several mourners attacked the photographer, punching him on the face and head, and took away both cameras. Soldiers nearby intervened to break up the crowd, and retrieved one of the cameras.
