Ukraine, NATO, US: Russian forces inside Ukraine

NOVOAZOVSK, Ukraine (AP) - "Russian forces have entered Ukraine," the country's president declared today, cancelling a foreign trip and calling an emergency meeting of his security council. Reports from analysts to separatist rebels to NATO and U.S. officials backed up that assessment. President Petro Poroshenko summoned the council as the strategic southeastern town of Novoazovsk appeared firmly under the control of separatists and their Russian backers, a new front in the war in eastern Ukraine between the separatists and Poroshenko's government in Kiev.
