Taliban officials said three people were killed and 16 others badly wounded in two bomb explosions that hit Afghanistan’s biggest military hospital in Kabul on Tuesday.
Interior ministry spokesman Qari Saeed Khosty said the explosions happened at the entrance of the 400-bed Sardar Mohammad Daud Khan hospital.
Although no suspects have been named in the twin blasts, witnesses said a number of Islamic State fighters entered the hospital and clashed with security forces.
Bomb explosions have become frequent in Afghanistan since the Taliban took over the government.
Last October 15, 37 people were reported killed and 70 others badly injured when three suicide bombers detonated a bomb at a Shiite mosque in the southern Afghan city of Kandahar during Friday prayers.
An eyewitness said three suicide attackers, one of whom blew himself up at the entrance to the mosque while the two others set off their devices inside the building.
Many suspect the bombings is the handiwork of ISIS, an extremist group, which is opposed to the ruling Taliban and view Shiite Muslims as apostates who deserve to die.
Another eyewitness said he heard three blasts, one at the main door of the mosque, another at a southern area, and a third where worshippers clean themselves.
