BUENOS AIRES, October 16 (RIA Novosti) - Drug police in Uruguay have seized a huge shipment of cocaine with a street value of $100 million, Latin American media reported on Friday.

More than 2 tons of drugs were discovered on board an English-flagged yacht in the port of Santa Lucia, some 25 km to the west of the Uruguayan capital, Montevideo, media reports said.

Two men, Uruguayan and Serbian nationals, who reportedly intended to load the drug cargo on board an ocean liner travelling to Europe, were detained by police.

Media quoted police as saying the drugs were brought to Uruguay from Colombia via Argentina.

The operation had been prepared for two months and involved drug police officers from Argentina, the United States, Uruguay and Serbia.

Police raids took place also in Argentina's capital, Buenos Aires, and in Serbia's capital, Belgrade, where three suspects were detained, reports said.

Argentina has long been a transshipment point for drug trafficking from Latin America to Europe and ex-Soviet states.

Earlier this year, a Moscow court sentenced six smugglers to prison terms of up to 18 years for trafficking drugs from Argentina to Russia.
