The European Union's foreign policy chief, Federica Mogherini, said today that reports of military reinforcements in Ukraine's separatist areas were a "very worrying development" and called on Russia to prevent further movement of "troops, weapons and equipment".
"The most recent reports by the OSCE Special Monitoring Mission in Ukraine about convoys in separatist held areas with substantial amounts of heavy weapons, tanks and troops without insignia moving westwards represent a very worrying development," said Mogherini in a statement. She also called on all sides to show "restraint".
