"We call on the Security Council now to do everything possible to stop aggression of the Russian Federation to Ukraine. There is still a chance," Ukrainian Ambassador Yuriy Sergeyev said yesterday.
Russian troops entered Ukrainian territory illegally as an "act of aggression against the state" and "their number is increasing every coming hour," he added.
Sergeyev called for the deployment of international monitors and said Russia had "brutally violated the basic principles of the charter of the United Nations."
