In China, a gas explosion inside a coal mine has killed 15 workers and injured another nine in the northern province of Shanxi. Last year a review of the mine found it failed to provide adequate training for workers. China’s mines are the deadliest in the world, accounting for about 80% of mining deaths worldwide. The Chinese mining explosion came on the heels of a gas pipeline explosion in Bangladesh Sunday, which killed seven people and hospitalized another 25 people southeast of the capital Dhaka.
