AT least 42 people were killed on Friday and Saturday in heavy fighting between government troops and militia opponents battling for control of the port in the Somali capital Mogadishu, residents said. The fighting, the most intense in the city in months, pitted soldiers of the Transitional National Government of President Abdiqassim Salad Hassan against fighters of warlord Hussein Aideed. Residents said well over 100 people had been wounded. The 18 hours of violence, which began late on Friday afternoon, subsided on Saturday morning with the port and its immediate vicinity under the control of Aideed’s militiamen, the residents said. Arms used were delivered from Ethiopia to the headquarters of Muse Sudi Yalahow in southwest Mogadishu, one of several warlords including Aideed who met in Addis Ababa in March to establish a rival government to Salad Hassan’s administration.
