Visuals have emerged of the Pakistani airstrike at a hospital for drug users in Kabul, leaving at least 400 dead and 350 injured in the Afghan capital.
The attack comes amid ongoing fighting between the two neighboring countries, which has been ongoing for three weeks.
Afghanistan's deputy government spokesman Hamdullah Fitrat confirmed the airstrike hit the hospital at around 9pm local time on Monday, destroying large sections of the 2,000-bed facility.
The death toll has reached 400 people, while about 250 people have been reported injured.
Local television stations shared footage showing emergency workers using flashlights as they carried out casualties while firefighters struggled to extinguish flames among the ruins of a building.
Kabul blamed Pakistan for the strike, but Islamabad dismissed the allegations as baseless, saying no hospital was targeted in Kabul.
