Pakistani officials said on Sunday, a bomb explosion killed at least 15 people and wounded 50 at a crowded market in a mainly Shia area in northwestern region of Pakistan.
The bomb attack occurred at Eidgah Sunday bazaar in Parachinar, the capital of Kurram district.
Condition of the wounded victims is severe as a doctor at the headquarter's hospital put it, most of the injured were in “critical condition” and added that the death toll could rise.
Kurram region is known for sectarian clashes between Sunnis and Shiites. The Shiites make up roughly 20 percent of Pakistan’s 200 million people.
No group immediately claimed responsibility for the attack.
Pakistan's seven tribal districts near the Afghan border have long been hotbeds of Taliban and Al Qaeda militancy.
The Pakistani Army has been fighting against Taliban militants since June 2014. More than 3,000 militants and approximately 300 soldiers have been killed since the operation started.
