MORE than 20 people have been killed and 16 injured in a gun and bomb attack claimed by Isis on a Kabul military hospital.

The attackers targeted the 400-bed Sardar Daud Khan hospital, which had civilians among the patients, with two explosions outside the building in Afghanistan’s capital.

Gunmen then broke into the hospital groups and fired indiscriminately, according to officials.

Isis affiliate IS-K later claimed responsibility.

Doctor Sayed Ahad said he was sent to seek shelter in a safe room during the attack and could hear guns being fired.

He told broadcaster EVN that one of the blasts was a suicide attack.

“As an Afghan citizen, I am really tired of this war, suicide and explosions,” he said. “How long do we have to endure this misery?”

Taliban spokesman Bilal Karimi said that their fighters shot and killed four attackers and captured one alive.

Witnesses said they saw two helicopters over the area during the assault.

Taliban spokesman Zabihullah Mujahid confirmed that special forces were dropped by helicopter, adding that attackers were killed at the entrance or in the building’s courtyard.

All the assailants were killed in 15 minutes, he said.

He said that two women and a child were among those killed.

The Taliban’s response would have been the first time its forces have used aircraft captured from the previous government during an operation.

Today’s attack is the latest by the Isis affiliate to hit Afghanistan since the Taliban took control in August.

A bombing by Is-K at Kabul International Airport, while Western forces scrambled to withdraw from the war-torn country, killed more than 150 civilians and 13 US soldiers.
