More than 130 kilograms of cocaine have washed on Romanian shores, prompting a massive police search operation that included helicopters and more than 300 officers on Romania's coast along the Black Sea on Sunday, police said.

The police urged local residents in Constanta not to open the bags of cocaine washing up ashore: they said the drug, believed to be 90% pure, could pose a danger to human health. The cocaine is worth hundreds of millions of euros, police said, according to Euronews.

A lot of cocaine has been found in Romania recently in other incidents. More than a tonne, in 36 separate bags, was found in a capsized boat in the delta of the Danube river last month. Another 200 kilos were discovered in the Black Sea on April 2, the police said.

Local media Digi24 reported that the search on Sunday was covering 90 kilometers along the coastline.

As UNIAN reported earlier, Ukrainian law enforcers have blocked an attempt to ship to the EU a large batch of cocaine in a container with bananas, which had been imported into Ukraine, according to the SBU Office in Odesa region.

The cost of the batch found in a vessel at the Yuzhny seaport amounted to over $51 million.
