Ukrainian national guard soldiers fired shots in the air when a crowd of pro-Russian separatists attacked their base near the eastern city of Mariupol on Wednesday, the interior ministry said in a statement.
A crowd of armed protesters arrived at the base and demanded that the national guard troops back their revolt against the country's new pro-Western government, the statement said.
When the crowd refused to disperse and tried to enter the base, the national guard troops shot into the air, the statement said.
It did not say whether anyone was injured in the attack. (Reuters)
