Hundreds of medical facilities in Afghanistan are at risk of imminent closure because the Western donors who finance them are barred from dealing with the new Taliban government, a World Health Organization official said on Monday.

Axar.az reports that around 90% of 2,300 health facilities across the country might have to close as soon as this week, the UN health agency's regional emergency director, Rick Brennan, told Reuters in an interview.

He said may Western donors had regulations which prevented them from dealing with the Taliban, without going into further detail.

"We are going to have a pause in operations in a large proportion of those (health facilities). By some estimates up to 90% will cease functioning probably later in the week and that will be associated with increased illness and death," Brennan said.
