A Somali police official says a suicide bomber has detonated an explosives-laden car outside the United Nations Mine Action Service offices in Mogadishu, killing three other people.
Captain Mohamed Hussein said Tuesday unlike previous attacks blamed on the al-Qaida-linked militant group al-Shabab, gunmen did not accompany the suicide bomber.
No group has claimed responsibility for the attack which is in a highly guarded area because of the UN offices and African Union troops' base. Suspicion has, however, fallen on al-Shabab, which is waging an insurgency against Somalia's weak UN-backed government.
Al-Shabab wants to establish an Islamic emirate in the country based on a strict form of Islam.
