The security service said an “anti-terrorist” operation was in progress. Russian Prime Minister Dmitry Medvedev wrote on his page at Facebook: “Blood has once again been spilt in Ukraine. The country is on the brink of civil war.” On the other part, President Oleksander Turchinov told to the Ukrainian parliament: “The anti-terrorist operation began during the night in the north of Donetsk region. But it will take place in stages, responsibly, in a considered way. I once again stress: the aim of these operations is to defend the citizens of Ukraine.” In Kiev, a radical pro-Russian candidate running for Ukrainian presidential elections was beaten up by an angry crowd. Moscow reacted accusing Kiev of provoking the crisis by ignoring the rights of citizens who use Russian as their first language. But even a report by the U.N. human rights office, which concluded that no systematic attacks against the ethnic Russian community was called by Moscow as “one-sided, politicized and apparently fabricated.” NATO Secretary-General Anders Fogh Rasmussen accused Moscow of involvement in the rebellions.
