Another 3,640 people have been wounded in the magnitude 6 quake that struck on Sunday as aid organisations struggle to reach survivors.

Rescuers have recovered hundreds of bodies from mountainous areas of southeastern Afghanistan, which was hit by a major earthquake at the weekend, taking the death toll to more than 2,200, according to a Taliban government spokesperson.

Previous estimates said some 1,400 people were killed. Taliban spokesperson Hamdullah Fitrat said on Thursday that the updated death toll was 2,205.

“Tents have been set up for people, and the delivery of first aid and emergency supplies is ongoing,” Fitrat said.

A third earthquake struck the region on Thursday, as search and rescue efforts were continuing. No new deaths have yet been reported after the magnitude 6.2 earthquake. Sunday’s quake was one of the deadliest in recent times due, in part, to how shallow it was, with its epicentre at a depth of about eight kilometres (five miles).
