A car bomb detonated outside the Frontier Constabulary headquarters in Quetta, Balochistan, following initial gunfire from militants; the explosion was heard miles away.
At least eight people killed and several (possibly up to 19) injured; emergency services rushed victims to hospitals, with fears of a rising death toll.
No immediate claim of responsibility, but Baloch separatist groups like the BLA are suspected amid ongoing insurgency in the province.
