On August 24, 2021, Ukraine celebrated its 30th Independence Day. In honour of this date, a naval parade took place in Odesa. Odesa is one of those Ukrainian ports where the Ukrainian naval forces were relocated after the occupation of Crimea by Russia.
The large anti-submarine ship “Vice-Admiral Kulakov” and the tugboat “Altai” planned to call at the port of Ceuta on August 18 and stay there for three days.
Earlier, Ukraine could analyze and monitor such an environmental catastrophe as oil spill, because the Russian port of Novorossiysk is located near Crimea. But after Russia had occupied the peninsula, Ukrainian scientists were deprived of the opportunity to do such work.
Russian prosecutors have opened a criminal probe into an oil spill off the country's Black Sea coast that appeared to be far bigger than initially thought.
Clearly, the submarine’s propulsion system was not working for a period of time, but we don’t know why. Incidents involving nuclear submarines, especially ones operated by Russia/Soviet Union, have long been a cause of potential international concern
The Ukrainian Ministry of Defence blames Russia for the attack, saying that the country is intentionally conducting information operations against Ukraine.
According to the Russian military, HMS Defender was told to change course, and when it failed to do so, a Russian border patrol ship sent several warning shots. The UK government rejected Russia's account of the incident and denied that any warning shots had been fired.
