A car bomb exploded in Mogadishu Tuesday near a meeting involving two Kenyan ministers after Shebab rebels promised Nairobi all-out retaliation for its unprecedented military operation inside Somalia. The car bomb exploded near the foreign ministry where Kenya''s Defence Minister Yusuf Haji and Foreign Minister Moses Wetangula were meeting officials from the Western-backed Somali transitional government. "There was heavy explosion near the foreign affairs ministry building and initial reports are indicating a car laden with explosives detonated. We are still investigating the incident," Mohamed Adan, a Somali official said. Reports said two people were killed and 15 others injured in the explosion. A suicide attack two weeks ago killed 30 people, mostly students and injured many others.
