Anti-government protesters take tyres at a barricade at the site of clashes with riot police in Kiev January 25, 2014. Ukrainian President Viktor Yanukovich, in what appeared to be an offer of concessions to the opposition amid violent protests against his rule, pledged on Friday to reshuffle the government next week and to amend sweeping anti-protest laws.

Ukrainian protesters stood their ground after a sweep by riot police and their leaders dismissed an offer of talks from a president they say must quit for favouring ties with Russia over the European Union.
