Some survivors of the attack on the 400-Bed Sardar Daud Hospital Complex claim that the attackers were placed inside the facility before it happened.
They said an explosives-laden vehicle was detonated right in front of the main gate of the hospital and later another explosion happened in the second floor.
The Ministry of Defense says they have not collected sufficient information about the details of the attack which killed dozens of people.
The hospital has four security check points, run by the Afghan National Army soldiers, according to TOLOnews’ Abdul Wali Arian who visited the attack scene a day after it occurred.
“It is possible that someone (inside) had a hand in this attack. The attackers would have been helped to enter the hospital from the back door. Because it was impossible for them to enter from this way (front gate),” said Ghulam Yahya, an army solider, who survived the incident.
Arian said it takes 10 minutes to reach the part of the complex where the attackers were placed.
Aimal, a doctor who survived the attack, said he was trapped under the bullets for three hours.
“I heard blasts on the lower floor. I heard blasts from hand grenades and there was a lot of gunfire,” he said.
“The attackers were already in position. Those who say they have entered from the back door, they should know that the door is locked. If they did indeed enter from the back door, why they didn’t go the office of the army health director? Why they didn’t kill the director? Why did they come towards the hospital building?” he added.
Many parts of the hospital’s surroundings are protected by T-walls.
Sources now say at least 50 people including 38 Afghan Defense and Security Force (ANDSF) members and 12 civilians were killed and 91 others including 61 ANDSF members were wounded in the attack.
The coordinated attack was reportedly carried out by five Daesh militants – including three Afghanistan and two Tajikistan nationals.
“This must be investigated and it should be found that how they [attackers] entered the hospital and from which door they entered. The attacker[s] detonated their explosives inside the gate not outside,” the MoD spokesman Dawlat Waziri said.
