The European Union on Saturday warned that the apparent incursion of Russian troops on Ukrainian soil pushes the conflict closer to a point of no return, with new economic sanctions being drawn up to make Moscow reconsider its position. Ukrainian President Petro Poroshenko,
who briefed a summit of the 28-nation EU's leaders in Brussels, said a strong response was needed to the "military aggression and terror" facing his country.
"Thousands of the foreign troops and hundreds of the foreign tanks are now on the territory of Ukraine," Poroshenko told reporters in English. "There is a very high risk not only for peace and stability for Ukraine, but for the whole peace and stability of Europe."
