At least 11 Afghan soldiers are dead after Islamic State militants attacked troops guarding a military academy in the capital, Kabul. Sixteen others were wounded.
The attack was the latest in a wave of relentless violence in Kabul this month unleashed by the Taliban and the rival Islamic State group. The violence has killed scores and left hundreds wounded.
Witnesses said Monday's attack started before dawn, and that fighting continued long after daybreak.
Afghan Defense Ministry spokesman Dawlat Waziri says a suicide bomber struck the military unit responsible for providing security for the academy, setting off a gunbattle with the troops.
The spokesman says at least five insurgents were involved in the morning assault. He said two of the attackers were killed in the gunbattle, two detonated their suicide vests and one was arrested.
