New Delhi, Nov 2 : At least 13 people were injured in a blast near the Chief Chowk in Balochistan's Kharan on Tuesday afternoon, Samaa TV reported. The injured people have been moved to the hospital. The police and Rangers personnel have, on the other hand, cordoned off the area. A search operation is underway. According to the police, the bomb was installed on a motorcycle. Around five to four kg of explosives were used in the attack, the report said. Balochistan Chief Minister Abdul Qudus Bizenjo has condemned the attack and called it "an attempt of anti-nationalist organisations to disrupt peace in the province".
