At least 1,570 homes have been damaged or destroyed by flooding from heavy rains over the weekend in Panama.
Ivan Batista of the Panamanian Red Cross said bulldozers are being used to remove earth from a mudslide that may have buried two Red Cross workers.
Mr Batista said that the two workers disappeared late on Sunday when the rains and a mudslide washed out the road they were travelling on.
National Civil Defence Director Arturo Alvarado said that about 6,500 people have been forced from their homes along the Caribbean coast.
Rivers in the region overflowed their banks over the weekend, damaging homes, roads and bridges. Rains tapered off yesterday.
