Hazaras in Quetta staged a protest for the second day after a blast killed 20 people, including two children, in Hazarganji on Friday.
The protest has been continuing for 24 consecutive hours. Their main demand is better security for their community.
The blast in Hazarganji, a predominantly Hazara neighbourhood, occurred at a vegetable market. A Frontier Constabulary soldier was also killed in the blast. Over 40 people were injured, most of them Hazaras.
Saturday's protest saw hundreds of Hazaras blocking the Western Bypass. They set tyres on fire to stop traffic and sat on the road. The protesters included women and young children.
