Gas Blast Kills 2 at Montreal Shelter

An explosion from a severed gas line destroyed a center for homeless people run by the Grey Nuns in Montreal, killing two women and injuring about 20 other people, authorities said. One nun believed to be in her 70s was missing. The explosion sheared off a wall of the three-story stone building, spilling rubble into the street in historic Old Montreal. The municipal gas company said a private contractor ruptured a gas pipe while trying to adjust a meter. No one lived at the shelter, which was used to provide meals and shelter for homeless people during the day.
