KARACHI : A 5.6-magnitude earthquake hit south Pakistan early on Friday, seismologists said. The quake struck at 00:28 am local time at the relatively shallow depth of five kilometres, 32 kilometres west of Warah in Sindh, the US Geological Survey (USGS) said. In an initial assessment, the USGS said there was a low likelihood of casualties and damage. Pakistan was hit by a 7.6-magnitude earthquake on October 8, 2005, that killed more than 73,000 people and left about 3.5 million homeless, mainly in Azad Kashmir and parts of Khyber Pakhtunkhwa.
