Rescue teams struggled Wednesday to reach survivors days after a powerful earthquake in eastern Afghanistan left more than 1,400 people dead, as access to remote areas remained obstructed.

A magnitude 6.0 shallow earthquake hit the mountainous region bordering Pakistan late Sunday, collapsing mud-brick homes on families as they slept.

Fearful of the near-constant aftershocks, people huddled in the open or struggled to unearth those trapped under the heaps of flattened buildings.
