Some of the protesters standing on Kyiv's Independence Square have been injured.

Their precise number is unknown, but several people have been taken to ambulance vehicles, an Interfax correspondent reports.

Most approaches to the Kyiv center were blocked early on Wednesday morning.

Traffic police posts were placed on Parkova Road, Klovsky Descent, Besarabska Square, Pushkinska and Prorizna Streets and Tarasa Shevchenka Boulevard, an Interfax-Ukraine correspondent reported.

Traffic police officers gave an informal advice not to go to the city center.
