Dozens of pro-Russian activists have been freed from police detention in Ukraine's southern port of Odesa, after a crowd of some 2,000 surrounded the police headquarters demanding their release.
The pro-Russia crowd forced a gate and broke windows at the police station as police officers tried to stop them from entering.
Ukraine's Interior Ministry said in a statement today that 67 pro-Russia activists were released. It was not immediately clear whether others were still being held.
The activists had been detained after a fire and fighting in the port city that left more than 40 people dead on May 2.
Most of the victims died in a blaze apparently started by firebombs thrown inside the building where pro-Russia activists had sought refuge amid street fighting with pro-Ukrainian demonstrators.
Ukrainian Prime Minister Arseniy Yatsenyuk visited Odesa May 4 and accused Russia of engineering the violence.
