Guatemala's death toll following Hurricane Stan has risen past 500, as rescuers continue to retrieve bodies from whole villages buried by mudslides.

Guatemalan officials said Saturday that rescuers may find hundreds more. Already, Hurricane Stan has become the country's worst natural disaster. Its death toll has surpassed that of Hurricane Mitch, which killed 268 people in 1998.

Guatemala was the worst-hit of the nations ravaged by Stan, which struck Central America during the past week, and Mexico's Gulf Coast Tuesday. Officials say at least 67 people were killed in El Salvador. At least 15 deaths are reported in Mexico, and at least 10 in Nicaragua.

Thousands of people in the region are in shelters or homeless after their homes were covered in mud or washed away.
