Somalia Islamists al-Shabab ambush Ethiopia troops

An attack on Ethiopian troops in Somalia by the Islamist militant group al-Shabab has killed at least 40 troops, reports say.
Ethiopian soldiers, and some Somali troops, were ambushed by the militants in Yurkut village in the central region of Geddo early on Saturday.
Clashes continued for four hours.
A BBC correspondent in the capital Mogadishu says it is the most intense fighting since Ethiopian troops entered the country last November.
