KABUL — Bulldozers dug pits in a cemetery in Kabul ahead of a mass funeral for some victims of an airstrike on a drug rehabilitation hospital. The mass funeral in Kabul was for victims from Kabul province whose bodies had already been identified.

Afghan officials have put the death toll from the strike at 408 people and the number of wounded at 265. The reported death and injury toll from the strike could not be independently verified.

The 2,000-bed Omid Addiction Treatment Hospital was hit at around 9 p.m. on Monday. Bodies were still being pulled from the smoldering remains of the hospital on Tuesday morning.

The airstrike caused an intense fire at the hospital, with rescue crews combing through the wreckage with flashlights late into Monday night as firefighters struggled to extinguish the blaze. Light rain fell in Kabul as ambulances lined up outside the cemetery and unloaded plain wooden caskets.

Pakistan rejects the accusation that it targeted the Omid Addiction Treatment Hospital, insisting its strikes were against military facilities. Pakistan dismissed Afghan claims of hundreds of casualties as propaganda.

"Technical support infrastructure and ammunition storage facilities at two locations in Kabul were effectively destroyed," Information Minister Attaullah Tarar said. "The visible secondary detonations after the strikes clearly indicate the presence of large ammunition depots."

Victims from other provinces were to be transported to their home provinces for burial. The hospital site is near Kabul's international airport and adjacent to the former NATO military base Camp Phoenix.

The 2,000-bed Omid Addiction Treatment Hospital had been renamed and expanded about a year earlier from a previously existing treatment facility as part of the Taliban government's efforts to combat drug addiction. Afghanistan's poppy fields have been the source of much of the world's heroin, and decades of conflict and widespread poverty have fueled drug addiction in the country.

The conflict between Afghanistan and Pakistan began in late February and has included repeated cross-border clashes as well as airstrikes inside Afghanistan, including in Kabul. Pakistan accuses Afghanistan of providing a safe haven for militants who carry out attacks inside Pakistan, especially the Pakistani Taliban. Afghanistan denies providing a safe haven to militants.

"Pakistan offers this gesture in good faith and in keeping with the Islamic norms," Tarar said about a temporary pause in strikes. "In case of any cross-border attack, drone attack or any terrorist incident inside Pakistan, the operations will immediately resume with renewed intensity."
