QUETTA: Four rockets slammed into Kohlu on Wednesday, shattering windows at several homes, an official said. No one was reported injured in the attack. Two rockets landed in a field near the homes of Water and Power Development Authority (WAPDA) workers in Kohlu, said Frontier Corps Lt Col Rizwan Malik. The two other rockets hit a wall around the houses. The blasts shattered windows but no one was injured, he added. No one claimed responsibility and Lt Col Malik would not speculate who might be behind the attack. Separately, saboteurs destroyed four power transformers by shooting at them in the Nushki area on Wednesday, resulting in a complete power blackout. The saboteurs managed to escape. Concerned authorities are working to restore electricity to the area.
