At least five protesters have died and dozens have been injured as fresh clashes between rioters and police erupt in central Kiev on Tuesday.
Protesters burnt tyres and threw molotov cocktails whilst police retaliated with tear gas and rubber bullets in an attempt to disperse the crowds. At least 37 police officers have also been injured in the protests.
Earlier in the day the Security Service of Ukraine (SBU) and the Ukrainian Ministry of Interior released a statement setting 18:00 (16:00 GMT) as a deadline which protesters must meet to end the fresh wave of unrest in Kiev.
A statement issued by the SBU urges the protesters to return to the negotiation table and threatens the opposition with the use of force, in accordance with the Ukrainian law, if they do not comply.
