European Union Enlargement Commissioner Stefan Fuele (2nd L) talks with the head of the Ukrainian opposition UDAR (Punch) party Vitalii Klitshko (L) and the head of the opposition Svoboda party Oleh Tyagnybok (R) during his meeting with Ukrainian opposition leaders in Kiev on January 24, 2014. Ukrainian protesters today expanded their protest camp in Kiev closer to the administration of President Viktor Yanukovych, after crisis talks to end Ukraine's worst crisis since its 1991 independence ended in deadlock. After five days of clashes that activists say left five dead, Ukraine's three main opposition leaders held several hours of talks with Yanukovych late on January 23 but the minor concessions they announced were greeted with derision by protesters.
