Six Russian special forces armored personnel carriers broke through the gates of Belbek Airbase, firing warning shots into the air, a spokesman for Ukraines Ministry of Defense in Crimea, Vladislav Seleznyov, told CNN.
One journalist was injured in the attack, he said.
Once inside, the Russians lined up the Ukrainians in one place, he said.
In a separate incident, pro-Russian self-defense forces stormed the Novofederoskoe military base, also in Crimea, taking control of it, a Ukraine Defense Ministry spokesman said Saturday.
Ukrainian forces on the base threw smoke bombs during the incident and retreated to the bases headquarters, according to Seleznev, in a Facebook posting.
The bases aviation brigade then sang the Ukrainian national anthem, lowered the Ukrainian flag and left the base, he said.
Very sad for these folks.....there was nothing they were going to do at this point against such an overwhelming force.
