The public organization Russian Community of Sevastopol has asked the Russian administration to protect the Russian population of Sevastopol and Crimea.
"We are asking Russia on behalf of residents of the hero city of Sevastopol to intervene in this situation and protect the Russian population of Crimea," the public organization said in an address posted on its website.
February 18 "essentially became a point of no return in the contemporary history of Ukraine," the document says.
"In the light of these events, the Russian population of Crimea and Sevastopol is under the threat of genocide," the address says.
The authors of the address also believe that the NATO forces may "soon enter the territory of Ukraine, which is de facto ungoverned, to help the peaceful protesters, as happened in Yugoslavia."
