At least two people have been killed in the clashes
Security forces and armed attackers are locked in a bitter battle inside the 400-bed Sardar Mohammad Daud Khan hospital in Kabul.
At least one of the attackers entered the building dressed as a doctor and began to fire an AK-47.
Hospital worker Abdul Nadir said he saw one gunman, dressed in a doctor’s coat, pull out an AK-47 assault rifle and shoot a hospital worker and a patient.
The area around the hospital has been blocked off by security forces as they desperately attempt to regain control.
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.

No one has immediately claimed responsibility for the attack, although a number of account on social media suggest ISIS may be responsible the incident.
