Reports from Somalia say two people were killed and six others wounded when a bomb exploded in the capital, Mogadishu in what officials believe may have been an attempt to attack an African Union delegation.

Witnesses say the blast went off early Thursday on a road near where the AU delegation was scheduled to pass. The officials say the explosive device had been attached to a motorcycle which had been parked by the side of the road.

The AU team has been in Somalia to asses security for a regional peacekeeping force.  Somalia's new government had asked for AU peacekeepers to defend officials as they begin moving home from their current base in Kenya later this month.
