The attack on the Omid Addiction Treatment Hospital, which happened at about 21:00 local time (16:30 GMT), is the deadliest in recent violence between Pakistan and Afghanistan. The death toll has continued to rise, and the Taliban government says it believes the number of people killed is about 400, although this figure has yet to be confirmed. It was like doomsday," said Ahmad, 50, who was also receiving treatment at the facility - a former military training camp that was turned into a makeshift rehab centre a decade ago. It served as a military training compound used by the US and Nato, but the facility was later abandoned by the Americans and converted by the Afghan republic government around 2016 into a rehabilitation centre. After the Taliban seized control and set up their government in 2021, it continued to house patients as a detention and rehabilitation facility. At one point, the Taliban government said the number had reached 5,000 at the centre, which was designed to hold up to 2,000.
