About 1,000 Pakistani Shiites braved winter cold to block a major road in the city with funeral processions for some of the 92 people killed in the bombing of a billiards hall.
Protesters Friday lined up about 50 coffins along the street to press demands that the Pakistani military dispatch troops to Quetta to maintain order, the Khaama Press said.
Talks aimed at curbing the protests apparently made little progress Friday, Dawn News said.
A federal minister told reporters another meeting between government officials and Shiite leaders would take place Sunday in Karachi.
No one has claimed responsibility for the recent spate of bombings in Quetta. Militant Islamists linked to al-Qaida have been blamed for similar attacks in the past.
