KINSHASA, Congo — A fuel tanker overturned and burst into flames in eastern Congo, sparking a massive fire that killed at least 220 villagers and wounded more than 200 – some of whom had rushed to siphon leaking liquid from the vehicle illegally, the U.N. and local officials said Saturday. The truck overturned as it was trying to pass a mini-bus late Friday near the village of Sange, around 20 miles (30 kilometers) north of Uvira, a town near the Burundi border, said Mana Lungwe, manager of the Congolese oil company that owns the truck.
