Dozens of Ethiopian soldiers were killed by the Somali militant group Al-Shabaab in an attack on an army base in Somalia on Thursday morning.
The attack struck the Halgan army base some 300km from the capital Mogadishu.
"Our fighters stormed the Halgan base of AMISOM" Al-Shabaab spokesman Sheikh Abdiasis Abu Musab told Reuters. "We killed 43 AU soldiers from Ethiopia in the fighting. It was a huge blast. It destroyed the gate and parts of the base."
The attack was reportedly carried out at dawn, beginning with a suicide car bomb followed up by attacks by gunmen.
An AMISOM spokesman said the base had not fallen to Al-Shabaab, but did not give an exact casualty figure.
Al-Shabaab is dedicated to overthrowing the internationally recognized government in Somalia and establishing an Islamist theocratic state. It frequently launches attacks on African Union forces (AMISOM) who are attempting to restore order in the country.
Al-Shabaab pledged allegiance to Al-Qaeda in 2012.
The federal government controls only limited parts of the country and a civil war has been ongoing since 1991.
