At least three police officers, including a senior official, were killed in a suspected suicide blast in the southeastern city of Quetta on Thursday morning, police and local media reported.
A senior police official and two others died in Thursday's attack, which happened in a residential area in the southwestern city of Quetta. Reports confirmed that DIG's vehicle was badly damaged in the explosion.
"He was going from his home in Chaman Housing Scheme [area of the city] to his office when the blast occurred", said Naimatullah, who goes by only one name.
A provincial government spokesman, Anwar-ul Haq Kakar, condemned the attack, saying it "demonstrates the sacrifices police is making in the war against terror outfits in Baluchistan".
Images from the scene showed the mangled remains of his pick-up truck, with the front and passenger side of the vehicle appearing to bear the brunt of the blast. The parts of the alleged suicide bomber has been gathered for investigation.
At least six police commandos and a civilian were killed last month when an explosives-laden vehicle rammed into a security force's convoy on the Quetta-Sibi Highway.
The Tehreek-e-Taliban, also known as the Pakistani Taliban, claimed responsibility for the attack. Prolonged instability and violence in Balochistan southwestern province has become a headache for Pakistani authorities due to huge Chinese investment in the strategic China-Pakistan Economic Corridor (CPEC) project in the region.
