A large explosion outside a school in Somalia's capital Mogadishu on Thursday killed at least eight people, including students, witnesses said.
The extremist group al-Shabaab claimed responsibility for the attack.
The blast sent a plume of smoke above a busy part of Mogadishu during the morning rush hour.
Police spokesman Abdifatah Adam Hassan said eight people were killed and 17 others wounded.
Al-Shabaab in a statement carried by its Andalus radio said it targeted Western officials being escorted by the African Union (AU) peacekeeping convoy.
