A fast-moving fire tore through a three-storey building housing homeless people in northwestern Poland early Monday, killing at least 21 people and injuring 20 more, including an infant, officials said. The blaze broke out around 1 a.m. in a shelter for people waiting for social housing in Kamien Pomorski, some 370 miles (600 kilometers) from the Polish capital and near the Baltic Sea coast, said Pawel Fratczak, a spokesman for Poland's national firefighters. «While searching the building again this morning, we found the bodies of three more people, raising the toll to 21 dead,» Fratczak was quoted as saying by Associated Press.
