ISLAMABAD, Pakistan (CNN) -- At least 39 people were killed Friday morning when a suicide car bomb exploded near a crowded market in northwest Pakistan, police said.
The car bomb detonated shortly after 11 a.m. (1 a.m. ET) near the Kacha Pakha bazaar in the Kohat District in Pakistan's North West Frontier Province, said Dilwar Bangish, a district police chief.
The target was a Shia Muslim neighborhood and most of the victims were Shiite, said Ali Hassan of the district police. Another 54 were injured, also mostly Shia Muslims. The residents had received threats from Taliban in the past, he said.
Several shops and buildings collapsed in the blast, trapping victims. Thirty-six people were injured, according to police.
