President Zelensky has accused Russia of using similar tactics to ones seen in places like Chechnya, Syria, and obviously in Ukraine itself, where he says in this particular case, Russia has been bombing its own civilians. You can guarantee that Moscow will not accept that account.

One senior Russian scientist has called the spills the country's worst environmental catastrophe this century. They also affect occupied Ukraine, with contamination spreading to the northern shores of the Sea of Azov and along Crimea's Black Sea coast past Sevastopol. Colleagues at BBC Verify have studied some of the high-resolution satellite images detailing their extent.

Certain experts fear the pollution may eventually reach the coast of countries like Turkey, Romania and Bulgaria. Russia says nearly 2,500 tonnes of oil was spilt, although some estimates put it considerably higher. Either way, it's much more than another spill in the same area 18 years ago.

The Russian authorities have mounted a vast clean-up campaign, including this complex operation to pump the heavy oil out of the wrecked carcass of the grounded ship. They had to heat the dense fuel oil to 45 degrees Celsius to make it fluid enough to pump. Officials have deployed planes, drones, ships, booms and even divers to dig up and bag tar-like clumps from the seabed.

Environmentalists say such deposits would take decades to break down naturally. Efforts to mitigate December's disaster aside, questions also remain as to whether such types of aged tankers should have been at sea in the first place in winter. Some unconfirmed reports suggest the vessels were part of Russia's ghost fleet of tankers, used to evade Western sanctions.
