DUKKI - At least three miners were killed after a coal mine they were working in partially collapsed following a gas explosion in Balochistan’s coal-rich Dukki district on Monday morning. Three coal miners still remain trapped inside the mine, more than eight hours after the explosion. The six miners were working 1,700 feet deep inside the mine when a methane gas explosion resulted in a portion of the mine to collapse. The rescue workers were able to retrieve three bodies from the debris. The dead miners were identified as Muhammad Omar, Abdul Manan and Abdul Ghani.
