SANTIAGO, Chile -- A mudslide fueled by heavy rains swept over a village in southern Chile on Saturday, leaving at least five people dead and 15 missing, officials said.

Rain caused a river to overflow and the side of a hill to collapse, burying 20 of the 200 houses in Villa Santa Lucia in the Los Lagos region, located 790 miles south of Chile's capital, Santiago.

President Michelle Bachelet declared the region a catastrophe zone and confirmed the number of dead and missing. She met with her team of ministers to coordinate rescue and assistance efforts.
