Ukrainian Prime Minister Arseniy Yatsenyuk on Sunday vowed Ukraine would not give "an inch" of its territory to Russia, at a rally of thousands of people in Kiev in honour of 19th-century national hero Taras Shevchenko.
"This is our land. We will not give an inch of it. Russia and its president should know that," Yatsenyuk said after Russian forces and pro-Kremlin gunmen seized control of Ukraine's Crimea peninsula in the Black Sea.
