At least three people have died after a suicide bomber attacked an African Union peacekeeping base in the Somali capital of Mogadishu.
Incidents on four other bases which were at first feared to be co-ordinated attacks now appear to be false alarms, a Nairobi-based diplomat said.
The diplomat said the four other bases had sent reports that they had been attacked and were hearing explosions. The African Union is still investigating what those blasts were, with fears that they were a result of rocket-propelled grenades or land mines.
AU soldier Captain Prosper Hakizimana said a minivan had pulled up at one base and four men got out of the vehicle. One suicide bomber was shot when he attempted to enter the base and blew up.
Mr Hakizimana said two others were shot by AU forces and one was eventually captured. Two AU soldiers were killed and five others wounded in the attack. One soldier from a militia allied to the Somali government was also killed.
