The death toll in China's coal mine accident on Saturday has crossed one hundred. Hopes of finding more survivors suffered a blow today with the recovery of 12 bodies, raising the death toll to 104 in the nation's worst mining disaster in two years. Rescuers were braving mine shafts full of toxic gas in a desperate search for four workers still missing in the mine in Hegang city in the northeast, as grieving relatives of the victims angrily demanded answers.<br/><br/>Mine spokesman Zeng Jinguang told reporters that rescue operations are still continuing while confirming the latest death toll. The explosion had torn through the state-run mine in Heilongjiang province near the Russian border early Saturday after a build-up of gas. The tragedy was the latest in the country's notoriously dangerous mining industry.<br/><br/>
