A 6.8-magnitude earthquake has hit south-west Pakistan, in a region where at least 400 people died in a quake earlier this week.
The US Geological Survey said the quake struck approximately 250 kilometres (155 miles) north of the port city of Karachi.
There were no immediate reports of casualties or damage.
Local media reported that the quake affected Balochistan and Sindh regions.
It was also felt in Quetta, close to Pakistan’s border with Afghanistan, and Karachi.
At least 400 people died and hundreds were injured when a 7.7-magnitude quake hit the same region on 24 September.
Officials have estimated that about 300,000 people were affected by the earlier quake but relief and rescue efforts have been hampered by poor road networks and separatist militant activity.
