BELBEK AIR BASE, Crimea Pro-Russian forces stormed a Ukrainian air force base in Crimea, firing shots and smashing through concrete walls with armored personnel carriers, according to an Associated Press journalist. At least one person was wounded, the base commander said.
An APC also smashed open the front gate of the Belbek base near the port city of Sevastopol, according to footage provided by the Ukrainian Defense ministry. Two ambulances arrived and then departed shortly after. At least one of them was carrying what appeared to be a wounded person.
The Ukrainian commander of the base, Yuliy Mamchur, said there was at least one injury. He called his men together, they sang the Ukrainian national anthem and then stood at ease. He said they are going to turn over their weapons.
Russian forces have been seizing Ukrainian military facilities for several days in the Black Sea peninsula, which voted a week ago to secede and join Russia.
Elsewhere, more than 5,000 pro-Russia residents of a major city in Ukraine's east demonstrated in favor of holding a referendum on whether to seek to split off and become part of Russia.
The rally in Donetsk came less than a week after the Ukrainian region of Crimea approved secession in a referendum regarded as illegitimate by the Western countries. After the referendum, Russia moved to formally annex Crimea.
With Crimea now effectively under the control of Russian forces, which ring Ukrainian military bases on the strategic Black Sea peninsula, concern is rising that Ukraine's eastern regions will agitate for a similar move.
Russia has brought large military contingents to areas near the border with eastern Ukraine. Russian President Vladimir Putin has said there is no intention to move into eastern Ukraine, but the prospect of violence between pro- and anti-secession groups in the east could be used as a pretext for sending in troops.
Eastern Ukraine is the heartland of Ukraine's economically vital heavy industry and mining and the support base for Viktor Yanukovych, the Ukrainian president who fled to Russia last month after being ousted in the wake of three months of protests in the capital, Kiev.
Russia and Yanukovych supporters contend Yanukovych's ouster was a coup and allege that the authorities who then came to power are nationalists who would oppress the east's large ethnic Russian population.
