At least five Afghan National Army soldiers was killed and 10 wounded in an attack at a military academy in Kabul on Monday morning, Tolo News reported. Clashes between security forces and the attackers followed, and went on for five hours.

Ministry of Defence spokesperson Dawlat Waziri said two attackers had been killed, two blew themselves up, and one was arrested.

The Islamic State claimed responsibility for the attack, BBC reported, quoting the terror group’s news agency. However, an Afghan diplomat alleged on Twitter that the equipment found with the attackers had been procured by the Pakistani Army and supplied to the terrorist outfit Lashkar-e-Taiba and the Taliban. The diplomat, Majeed Qarar, wrote that the Pakistani Army had procured the military grade goggles used by the attackers as night vision goggles.

Heavy firing and explosions began near the Marshal Fahim National Defense University at around 5 am, The Guardian reported. Security forces have cordoned off the area.

The militants are believed to have been carrying rocket propelled grenade launchers, according to BBC. “The attack was against an army unit providing security for the academy and not the academy itself,” said Dawlat Waziri, spokesman for the Afghan defense ministry, according to The Telegraph.

The attack comes two days after a suicide bombing in the Capital city claimed 103 lives and left 235 people injured. A week earlier, Taliban terrorists had killed 22 people in a hotel in Kabul. At least 15 military cadets were killed in a suicide bombing at the military academy in October 2017.
