Relatives of people killed in a shack, flattened after fierce winds knocked down a tree, react in the Greater Buenos Aires district of Luis Guillon, January 31, 2005. Thunderstorms and torrential rains damaged many properties and vehicles, cutting power in the suburbs of Buenos Aires and some other Argentine cities. Seven people dead in a multiple-vehicle collision and two died elsewhere of electrocution and 200 people had to be evacuated. REUTERS/Enrique Marcarian EM
