UK Foreign Secretary William Hague has called on Russia to help push through a deal quickly on ending the crisis in Ukraine.
Pro-Russian activists in the east of the country are refusing to leave government buildings they have occupied in several cities, in defiance of Thursday's agreement.
Mr Hague says it was now crucial to put it into action.
