A 5.5-magnitude quake struck at 1:57 am Afghan time (2127 GMT Thursday) 85 km southeast of the Afghan capital Kabul and 140 km west of the Pakistani city of Peshawar, according to the US agency.

A 7.6-magnitude earthquake in northwest Pakistan and Kashmir in October 2005 killed 74,000 people and displaced 3.
