A pipeline carrying petroleum products exploded Tuesday in Nigeria's biggest city of Lagos, killing at least 16 people and injuring many others, the Red Cross said. The blast shook the heavily populated Adule Egba neighborhood after dawn, Nigerian Red Cross spokesman Umar Mairiga said. He said 16 bodies had been taken to the morgue, but that raging fires were hindering further recovery. Many people had been injured, he was quoted as saying by the Associated Press.
