The United Nations' humanitarian agency says the flooding situation in Suriname will probably get worse in the coming weeks as more heavy rains are forecast to hit the South American nation.

The U.N. Office for the Coordination of Humanitarian Affairs (OCHA) says Suriname urgently needs helicopters to deliver relief supplies to thousands of people displaced by the floods.

The U.N. agency says a Dutch team of disaster management experts arrived in Suriname Saturday to help aid efforts in the former Dutch colony. The agency says a Dutch relief plane is due to arrive in the country Monday carrying thousands of blankets, stretchers, tarpaulins and mosquito nets.

Suriname's military has also distributed food packages and hygiene items to the flood victims, but some villages in the Marowijne area of southeastern Suriname have yet to receive aid.

The government declared a disaster in parts of the country last week after several rivers burst their banks, flooding more than 150 villages deep in muddy water.

The Red Cross says 25,000 people were affected by the floods, and at least three people were killed.
