The Foreign Ministry of Ukraine has said that Russia's denunciation of the Russian-Ukrainian agreements on the presence of the Russian Black Sea Fleet in Crimea will mean that the latter is staying in Crimea illegally.

"If the Russian side denounces these agreements, the Russian fleet's presence in Crimea will violate the law," Ukraine's Foreign Ministry's spokesman Yevhen Perebyinis said a briefing on Friday.

He said that after such step "Russia should think about the withdrawal of the Russian Black Sea Fleet."
