A third ship is in trouble in the Black Sea, Reuters reports. Meanwhile, oil washed up along “tens of kilometers” of Russia’s Black Sea coast after two tankers were severely damaged by a storm over the weekend, a regional official said on Tuesday, according to the same sources.

The TASS news agency said the third ship, also a tanker, had issued a distress signal off Kavkaz port but was still intact, there was no oil leak and the crew was safe.

The first ship, the Volgoneft 212, was cut in half on Sunday in the Kerch Strait, between the Black Sea and the Sea of ​​Azov. The second, the Volgoneft 239, ran aground 80 meters (87 yards) offshore near the port of Taman in the strait.

The ships, both over 50 years old, were carrying about 9,200 metric tons (62,000 barrels) of oil products in total, TASS reported, raising fears that it could become one of the biggest environmental disasters to hit the region in years. Another agency, RIA, said the third vessel was from the same “aging” group of vessels.

Benjamin Kondratiev, governor of the southern Krasnodar region, said the fuel oil was found along the coast between the cities of Temryuk and Anapa.

“This morning, while monitoring the coastline, fuel oil stains were found. Oil products were washed ashore for several tens of kilometers,” he said.

Authorities said a local state of emergency was declared in four settlements in the Temryuk region and one village in the Anapa region due to an oil spill on the coastline.

A video posted by Zvezda TV showed a black oil-like substance along the coast in Anapa and stains along a beach.
