Muzhenko said three Ukrainian military were wounded and another three were injured during yesterday's events. He said the three wounded soldiers, according to the Ukrainian intelligence agencies, were hospitalized to the Kerch Pirogov hospital. Ukrainian boats had been tugged to the Kerch port.

Muzhenko stressed the response of the Russian Federation could be qualified as aggression since the territory of any vessel is a sovereign territory of the state to which it belongs.
