The entry into the sovereign territory of Ukraine of three Russian tanks is completely unacceptable.
Russia needs to commit to defusing tension. This means securing borders, withdrawing all military forces, and preventing further violence in eastern Ukraine. I urge the Russian leadership to work with President Poroshenko to restore stability and to regain the trust of the international community.
The Russian leadership should be clear that the international community stands ready to impose further sanctions if Moscow continues to provoke instability and does nothing to stop further violence.
