Emergency rescue teams on Tuesday were searching through the rubble of collapsed buildings hit by an earthquake that killed at least 1,400 people in eastern Afghanistan, according to the local authorities, as aid from foreign donors began to trickle in despite a reluctance to send funds to the Taliban-ruled country.

Entire villages remained cut off from emergency workers in the mountainous areas of Kunar, the hardest hit of four provinces affected by the 6.0-magnitude earthquake that rocked Afghanistan and parts of neighboring Pakistan on Sunday night.

The Red Crescent said on Tuesday that at least 3,251 people had been injured, and about 8,000 homes destroyed.

The Taliban evacuated more than 600 people to Jalalabad, the closest large city, and to Kabul, the capital, aboard three helicopters on Monday, according to Kate Carey, deputy head of the U.N. Office for the Coordination of Humanitarian Affairs in Afghanistan.

“They’re on the front lines of this rescue operation,” Ms. Carey said about the Taliban-led rescue efforts.
