A 6.8-magnitude earthquake has struck south-west Pakistan, in a region where at least 400 people died in a quake earlier this week.
Reports said the quake hit remote Awaran district, killing at least 12 people and burying others under rubble.
An official told Pakistan television that communications already damaged by last Tuesday's quake had been cut off.
Efforts to help thousands left homeless by the first earthquake have struggled against poor roads and separatists.
The US Geological Survey said Saturday's tremor measured 6.8 magnitude and could be felt across Balochistan province.
