Senior police official among dead as bomb explodes at mosque packed with dozens of people offering sunset prayers.
On Tuesday, at least two people were killed and more than 14 wounded after an improvised explosive device mounted on a motorcycle exploded in a market area.
That attack was claimed by Baloch separatist groups, who have been leading an armed uprising for independence for the ethnic Baloch areas of Balochistan province.
The province is Pakistan’s largest and is rich in mineral resources, but its rugged terrain and arid climate also make it the country’s least densely populated region.
No group immediately claimed responsibility for the attack on Friday.
“The roads are not safe anyway, but now we’re not even safe in our mosques,” said Azmatullah, who was wounded in Friday’s bombing.
