In such messages, propagandists claim that "Ukrainian nationalists" and, in particular, the Azov regiment defending Mariupol allegedly seized two foreign vessels in the Sea of Azov - the "Tsarevna" and the "Lady Augusta" and respectively - are holding their crews hostage. According to StopFake, propagandists also claim that the Azov regiment is allegedly firing mortars at civilian ships, preventing the evacuation of their crews. In fact, this is not true. According to StopFake, the information that Azov allegedly seized the Tzarevna was denied by two Bulgarian ministries at once - the Ministry of Foreign Affairs and the Ministry of Defense. StopFake was also unable to find any facts confirming the seizure of the ship Lady Augusta. "In addition, human rights activists have repeatedly recorded the fact that civilian ships were fired upon by Russian troops," the fact checkers wrote.
