Defence Ministry spokesman Dawlat Waziri said: "Our forces are there and there is heavy fighting”, although he declined to give any details about casualties. Afghanistan’s president, Ashraf Ghani, said: "There is an ongoing terrorist attack in a hospital which tramples all human values. "In all religions, a hospital is regarded as an immune site and attacking it is attacking the whole of Afghanistan." Unconfirmed reports suggest there are between three and five attackers who have positioned themselves on the upper floors of the hospital.
