Afghanistan lacks the medical supplies to treat those injured in an earthquake that killed 1,000 people this week, a senior official said, as an aftershock on Friday killed five more.

Authorities earlier ended a search in remote southeastern mountains for survivors of the 6.1 magnitude earthquake that struck early on Wednesday near the Pakistani border, about 160 km southeast of Kabul, the capital.

Friday's aftershock, in almost exactly the same place, was of magnitude 4.3, the U.S. Geological Survey said. A health ministry official said it killed five people, but there was no immediate word on the extent of new damage and injuries.
