Regular Russian troops are fighting in Ukraine, and it's a whole new game. The capture of Russian paratroopers in eastern Ukraine, and the quiet burials of other Russian solders, provided enough evidence that the nature of the conflict had changed. Now, though, Ukrainian President Petro Poroshenko has officially announced that "Russian troops were actually brought into Ukraine."
A second front has been opened against the Ukrainian Army in the rebellious Donetsk region. The Ukrainians were forced to give up the town of Novoazovsk on the Sea of Azov, not far from the strategic port of Mariupol, used by Kiev as the supply base for its anti-rebel operation.
Ukrainian military commanders say Russian troops entered the town. Although such claims have been made before, there's more reason than ever to believe them today.
