BBC Monitoring: Ukrainian police confirm they used tear gas against pro-European Union protesters in the capital Kiev today. The Kiev police department said protesters had thrown a smoke grenade at officers during what they said was an attempt to break into the Cabinet of Ministers building, but insisted that the police were within their rights to use tear gas in response and that "this was a one-off", Interfax-Ukraine news agency reports.
Unian news agency said police failed to stop protesters from attaching a red-and-black Ukrainian nationalist flag and a European Union flag to the flagpole outside the Cabinet of Ministers building.
