Two activists of the Svoboda all-Ukrainian Union have been detained for two days as part of the investigation into clashes that occurred on Sunday outside the cabinet building, Kyiv police say.

The court has not chosen any preventive measure for them.

"These people were detained as part of the criminal proceedings," the press service of Kyiv police told Interfax-Ukraine on Tuesday.

Earlier, a source told the agency that a court had ruled to put the two activists into custody as a pre-trial restriction.
