A bombing has targeted Pakistan's paramilitary force in the northwestern city of Peshawar, killing three officers and wounding at least five other people.
Police said the bomb went off on November 22 as a truck of the Frontier Constabulary paramilitary force was passing by.
Zulfiqar Babakhel, a spokesman for Peshawar's main hospital, said two of the wounded were critically injured.
Jamaat-ul-Ahrar, a breakaway faction of the banned Tehreek-i Taliban Pakistan (TTP), claimed responsibility for the attack.
Overall levels of militant-linked violence have fallen since the Pakistani military launched a large-scale operation in 2014 to wipe out militant bases in the northwestern tribal districts, but militant groups continued to carry out periodic bloody attacks.
