Witnesses in Somalia's capital say a grenade attack on a gathering of Yemeni nationals has killed one person and wounded four others.

The witnesses say the Yemeni community was electing a local leader in southern Mogadishu Thursday when a grenade was thrown into the meeting hall.

An officer from the Yemeni embassy in Mogadishu was among those present at the gathering.

It is not clear who was behind the attack.

Mogadishu has endured more than a year of chronic violence stemming from the conflict between Islamist militants and Ethiopian-backed government forces.

The country as a whole has been plagued by unrest since since warlords overthrew dictator Mohamed Siad Barre in 1991.
