An attack on a military hospital in Afghanistan has killed more than 30 people, the country's Defence Ministry has said.
"This egregious and morally reprehensible attack targeted people at their most vulnerable, while they were receiving treatment in the hospital, and also targeted the medical staff caring for them", said the UN Assistance Mission in Afghanistan.
Mohammad Nabi, a doctor at the hospital who escaped with a broken leg, said it had been hard to comprehend what was going on initially as the gunmen in doctors' white coats took out concealed weapons and began shooting.
First a suicide bomber blew himself up at the south gate to the Sardar Mohammed Daud Khan hospital, said Sediq Sediqqi, Afghan Interior Ministry spokesman.
Special security forces launched a clearance operation that ended after a lengthy gun battle with the militants who had taken up positions on the upper floors of the hospital.
The Afghan public health ministry also confirmed that two civilians had died and up to 12 more were injured before being transported to other hospitals.
As soldiers cleared the building, they discovered bodies and the number of casualties quickly grew.
