QUETTA, Pakistan (AP) — An explosion inside a coal mine in southwest Pakistan killed at least 32 miners Thursday and trapped 10 others underground in what officials believed to be life-threatening conditions as rescuers raced to reach them. It said the search and rescue operation was continuing, with rescue teams working to locate and recover the remaining trapped miners. Baloch said rescue operations would continue until all the trapped miners were found, but he added that officials believed the death toll likely would rise further. A coal miners’ labor union said it suspected negligence led to the explosion and called for action against those responsible. Deadly accidents are common in Pakistan’s coal mining industry, particularly in Baluchistan, where many mines lack adequate ventilation, gas monitoring systems and other basic safety measures.
