According to witnesses speach, a suicide car bomb aimed at African Union peacekeepers in the Somali capital missed its target and killed 14 civilians on Saturday, reported Reuters.
The bombing occurred days before a planned deployment of Ugandan and Burundian soldiers to beef up the current peacekeeping contingent.
Last month, the president resigned after months of government infighting. The Somali parliament is due to choose his replacement on Monday in Djibouti.
AU spokesman Bahoku Barigye said no peacekeepers were wounded in the attack. Last August, a car bomb attack targeted barracks housing Burundian peacekeepers.
Some analists say the withdrawal of an estimated 3,000 Ethiopian soldiers supporting the U.N.-backed interim government could leave a power vacuum.
They forecast more violence between rival armed groups who have been fighting the administration for two years.
Meanwhile others hope it could be positive, removing forces seen by many Somalis as occupiers and spurring more moderate Islamist factions to get involved in forming a new, inclusive government.
"No Somali wants the Ethiopians to stay, but there will be chaos whether they withdraw or not," Sheikh Abdullahi Sheikh Abu Yusuf, spokesman of Ahlu Sunna Waljamaca, a government-allied Sunni Islamist group, told Reuters.
