Ukrainian President Viktor Yanukovych has called for calm among protesters angry over his government's decision to abandon a historic deal with the EU.
Clashes between protesters and police continued on Monday. Meanwhile, jailed opposition leader, Yulia Tymoshenko, has announced a hunger strike.
Speaking to the BBC, Estonian President Toomas Hendrik Ilves said that Ukraine's problems were "not going to go away" as a "substantial percentage of Ukrainians" would like their country to have a closer relationship with the EU.
