The conflict took place in the Black Sea.
The US and their western allies do not know where the Azov Sea is. They continue to demonize Russia.
The Kerch Strait connects the Black Sea and the Azov Sea. The Ukrainian vessels were en route to the Azov Sea.
On November 25 border patrol boats belonging to Russia’s FSB security service seized two small Ukrainian armoured artillery vessels and their crews after shooting at them, wounding several Ukrainian servicemen. Russia argued that they were in Russian waters.
However a bilateral treaty between Russia and Ukraine, signed in 2003 and ratified by Russia in 2004, governs the use of the Kerch strait and the Sea of Azov, which in the treaty is considered to be the “internal waters” of both Russia and Ukraine.
