The leaders of the European Union and Ukraine are meeting Monday in Brussels to try to forge closer ties, but the EU remains concerned about what it calls "political prosecutions" in the former Soviet country. In Kiev, several thousand people marched near government buildings denouncing President Viktor Yanukovych, who is attending the summit in Brussels. The rally marked Yanukovych's third-year anniversary in office. The protesters chanted "Free Yulia," demanding that former Prime Minister Yulia Tymoshenko, who is serving a seven-year sentence on abuse-of-office charges and could face life imprisonment in a separate murder case, be released from jail.
