Around seven people, including five Balochistan Constabulary personnel, were killed after a bomber struck a security forces truck in Quetta.
The attack took place in the city's busy intersection of GPO Chowk, located in a high-security zone, not far from the provincial assembly. The suicide attack was later claimed by the Tehreek-e-Taliban Pakistan (TTP).
The Pakistan Army launched Operation Radd-ul-Fasaad, a military offensive against the 'latent threat of terrorism', in February last year.
