A bomb exploded in a grocery shop on Wednesday in Quetta, injuring 13 people, police said. The explosion hit the main market in the Balochistan capital and most of the injured were in a bus that was passing by, city police chief Mujeebur Rehman told AFP.
Twelve of the injured were released after receiving first aid in hospital but the bus driver was still undergoing treatment, he added. No one has claimed responsibility for the attack, Rehman said.
However previous attacks in the province have been blamed on tribal militants who want greater political rights and a bigger share of the region's ample natural resources.
