At least one person was killed and 10 others injured in an explosion in Quetta's Mission Road area on Tuesday evening, police said.
The bomb went off in a market located on Mission Road where most of the shops are owned by members of the Hazara community, Deputy Inspector General (DIG) Quetta Abdul Razzaq Cheema said.
He said the injured were rushed to nearby Civil Hospital Quetta for treatment.
"We are investigating the nature of the blast," the police officer told DawnNewsTV.
The explosion smashed the windows of nearby shops and shopping malls. Police reached the spot as an investigation into the incident went underway.
It was the third blast in the last fortnight in the provincial capital. All three attacks took place on consecutive Tuesdays.
On July 23, a blast had occurred in the Eastern Bypass area which left four people dead and 32 injured. And on July 30, an explosion near a police station in the city had left five people dead and 30 others injured.
The banned Tehreek-i-Taliban Pakistan had claimed responsibility for the blast near the police station.
The Balochistan cabinet, which was in session when last week's blast took place, had vowed to bring terrorists and their facilitators to justice and said that such attacks could not weaken the determination of the government against terrorists and their masters.
