Somali Islamist militant group al-Shabab says it has killed more than 40 Ethiopian soldiers in an attack on an African Union base in central Somalia.
Residents of Halgan told Reuters news agency that fighting began after a vehicle blew up near the base.
Reuters quotes a Somali military source saying “there are casualties on both sides”.
The AU mission (Amisom) supports the government as it fights to regain control of the country from al-Shabab.
Amisom officials have not confirmed the attack.
