Ukraine's president-elect is promising to negotiate an end to a pro-Russia insurgency in the east and says he's also willing to begin talks with Moscow.
Russia quickly welcomed the offer from 48-year-old chocolate magnate Petro Poroshenko. Foreign Minister Sergey Lavrov says Moscow is ready for direct dialogue with Ukraine's new president and Western mediation is not needed.
International observers are hailing Ukraine's presidential vote as a "genuine election," saying it was held freely and fairly.
At the same time, Ukraine's military has launched airstrikes against the separatists who have taken over the airport in the eastern city of Donetsk.
Poroshenko says the offensive against pro-Russia insurgents should last hours, not months.
A spokesman for Kiev's anti-terrorist operation writes on his Facebook account that the military presented an ultimatum earlier this afternoon to armed men who had occupied the airport to lay down the arms.
He says the gunmen didn't comply and the military launched an air strike.
