Ukrainian President Viktor Yanukovych has insisted that he and his government have "fulfilled all the obligations" to solve the crisis in the country. But the political opposition continued to "whip up" the situation, The statement was issued in Ukrainian, on the presidential website after weeks of often-violent anti-government protests in Kiev and other cities, led to a series of government concessions. It followed an announcement that Mr. Yanukovych, 63, was on sick leave. The presidential website said he had a respiratory illness and a high fever. The protests began in November, after President Yanukovych reversed a decision to sign a trade deal with the European Union, instead favouring a bailout deal with Russia to underpin Ukraine's ailing economy.
