A magnitude 5.5 quake has rattled northwest Pakistan causing panic as workers fled offices and children abandoned class rooms with no word yet on damage or casualties.
Arifullah Khan, an official at the meteorological department, says the epicentre of Wednesday's quake was near the northwestern city of Bannu.
The temblor was felt in the Swat Valley and Peshawar, the capital of Khyber Pakhtunkhwa province bordering Afghanistan.
The US Geological Survey put the magnitude at 5.1.
Officials say people fled their offices and homes in panic and were reciting verses from Islam's holy book. Teachers and schoolchildren also came out of classes.
A magnitude 7.6 quake in 2005 killed thousands of people in Pakistan and Kashmir, which is split between Pakistan and neighbouring India.
