Long lines, some stretching for blocks, formed outside grocery stores in the South American country's capital as residents search for scarce basic items such as detergent and chicken.

"I've visited six stores already today looking for detergent -- I can't find it anywhere," said Lisbeth Elsa, a 27-year-old janitor, waiting in line outside a supermarket in eastern Caracas. "We're wearing our dirty clothes again because we can't find it. At this point I'll buy whatever I can find."
