Suspected Baluch nationalists Sunday fired two rockets near a United Nations Refugee Agency (UNHCR) office and a police station in Southwestern Pakistani province of Baluchistan but there were no casualties, said police. One rocket landed near Sadar police station and one near UNHCR office in Quetta, the provincial capital, about 400 kilometers southwest of Islamabad, a police official told KUNA.He said there was no casualty, adding that the rockets exploded with a huge bang in nearby empty fields, panicking people and leaving 2-3 feet deep pits in the grounds. No group immediately took responsibility of the latest attack in the insurgency-hit in Pakistans largest but poorest of the four provinces, but authorities blame nationalist elements for most of such attacks.
