QUETTA: At least five people, including three schoolgirls and a policeman, were killed in a roadside blast in Pakistan’s southwestern Balochistan province on Friday morning, police said, in the latest incident of violence to hit the restive region. The blast appeared to target a police van passing by a girls school in the Mastung district of the province, according to police and local administration officials. Fateh Baloch, in-charge of the Mastung police station, said the police mobile van came under attack when it was on a routine patrol on Friday morning. “Five people, including a police constable and three minor schoolgirls, were killed and 13 others injured in the blast,” Baloch told Arab News. No group immediately claimed responsibility for the blast. “We have cordoned-off the area and are shifting the injured to the hospital,” Baz Muhammad Marri, the Mastung deputy commissioner, told Arab News. Balochistan, which borders Iran and Afghanistan and is home to major China-led projects such as a strategic port and a gold and copper mine, has been the site of a decades-long separatist insurgency by ethnic Baloch militants. The province has lately seen an increase in attacks by separatist militants. On Tuesday, five people were killed in an attack by armed men on the construction site of a small dam in Balochistan’s Panjgur district. The outlawed Baloch Liberation Army (BLA), the most prominent of several separatist groups, claimed responsibility for the attack along with killing of two other persons in Kech and Quetta districts. This month, 21 miners working at privately run coal mines were killed in an attack by unidentified gunmen. The separatists accuse the central government of exploiting Balochistan’s mineral and gas resources. The Pakistani state denies the allegation and says it is working to uplift the region through development initiatives. Besides Baloch separatists, the restive region also has a presence of religiously motivated militant groups, who frequently target police and security forces. Islamabad says militants mainly associated with the Pakistani Taliban frequently launch attacks from Afghanistan and has even blamed Kabul’s Afghan Taliban rulers for facilitating anti-Pakistan groups. Kabul denies the allegation. - This article originally appeared on Arab News Pakistan
