German Chancellor Angela Merkel says Russia's actions in Ukraine are a violation of international law and a threat to peace in Europe, RFE/RL reports.

Speaking bluntly in an address to Germany's parliament today, Merkel said, "Nothing justifies the direct or indirect participation of Russia in the fighting in Donetsk and Luhansk."

She told the Bundestag that Russia's actions have "called the peaceful order in Europe into question and are a violation of international law."

But she suggested there was no swift solution, saying, "Our efforts to overcome this crisis will require patience and staying power."

Germany has become increasingly frustrated over Moscow's refusal to heed Western calls to stop supporting pro-Russian separatists who have seized control of large parts of the Donetsk and Luhansk provinces in eastern Ukraine.

Close ties between Russia and Germany have been strained by the Ukraine crisis.
