A giant fire raging at Yangon’s largest dumpsite, in Hlaing Thaya Township, has been defying firefighters since Saturday. Making matters worse, noxious smoke from the fire has spread to nearby areas and hit downtown, choking some residents. On Wednesday, Yangon Mayor U Maung Maung Soe said 80 percent of the fire was under control. State Counselor Daw Aung San Suu Kyi has offered the union government’s help. As of Wednesday afternoon, though, firefighters and soldiers were still hard at work battling the blaze.
