Pro-Russia insurgents shot down two Ukrainian helicopters Friday and Ukraine reported many militants killed or wounded as the interim government in Kiev launched its first major offensive against an insurgency that has seized government buildings across the east.
The Kremlin said Kiev’s military move against the insurgents “destroyed” the two-week-old Geneva agreement on cooling Ukraine’s crisis. President Barack Obama said it was obvious to everyone now that the pro-Russia militants were not peaceful protesters and the U.N. Security Council held an emergency session in Ukraine at Russia’s request.
Fighting broke out around dawn near Slovyansk, a city 160 kilometers (100 miles) from the Russian border that has become the focus of the armed insurgency. Two helicopter crew members were killed in the crashes, both sides said, and the insurgents reported one member killed.
Acting President Oleksandr Turchynov later said two Ukrainian soldiers were killed and seven wounded in Friday’s clashes and the insurgents suffered significant losses, including many killed or injured. It was not clear if the two referred to the helicopter crew.
