Donetsk, Ukraine - A crowd of pro-Russian activists recaptured the regional administration building in the eastern Ukrainian city of Donetsk on Wednesday, hours after they were ejected by police.

The crowd of about 200 protesters threw open the front doors and re-entered the building despite a heavy police presence after a day-long demonstration following their ejection from a building they had held since Monday.

Earlier on Wednesday Ukraine flew its flag atop the building, replacing a Russian flag that had flown there since Saturday. Donetsk has seen the most persistent of a wave of pro-Russian demonstrations that broke out in southern and eastern cities on Saturday as President Vladimir Putin was declaring Russia's right to invade.

Kiev says the protests have been arranged by Moscow to justify military intervention.
