Poroshenko cancels visit to Turkey because of Russian troop deployments in Ukraine

Ukraine's president Petro Poroshenko has cancelled a visit to Turkey because of "Russian troop deployments" in the country's east. Reports indicate that in the latest offensive, pro-Russian rebels have opened a new front in the south by seizing the coastal town of Novoazovsk bbc.com. NATO says that it has detected a significant increase of Russian arms being supplied to the rebels over the past two weeks whereas Russia has been continuously denying that its forces have crossed Ukraine's border.
As a result, the United Nations Security Council is planning to hold an emergency meeting in New York on Thursday at 18:00 GMT to discuss the crisis.
NATO Brigadier General Niko Tak has admitted that there had been a "significant escalation in the level and sophistication of Russia's military interference in Ukraine" over the past two weeks.
It seems NATO has detected large quantities of advanced weapons, including air defense systems, artillery, tanks, and armored personnel carriers that have been transferred to separatist forces in eastern Ukraine. Obviously, Russia is reinforcing and resupplying separatist forces in a blatant attempt to change the momentum of the fighting, which is currently favoring the Ukrainian military.
More than 1,000 Russian troops are reportedly operating inside Ukraine, both supporting the separatists and fighting on their side and, so far, at least 2,119 people have been killed in the four months of fighting.
