KIEV, Aug. 28 (Xinhua) -- Ukrainian President Petro Poroshenko on Thursday canceled his planned visit to Turkey as tensions escalated in eastern Ukraine, the presidential press service said.
"I made the decision to cancel a working visit to the Republic of Turkey in connection with the rapidly deteriorating situation in Donetsk region," Poroshenko said.
Accusing Russia of "moving its troops into Ukraine", Poroshenko has called an emergency meeting of the National Security and Defense Council (NSDC) to "develop a plan for further action".
Poroshenko has also called on the international community to assess the "aggravation of the situation in Ukraine" and said that Kiev has appealed to its European partners to call an emergency meeting of the U.N. Security Council over the crisis.
Earlier Thursday, the NSDC said that "Russian troops" have captured the Ukrainian key port of Novoazovsk and several towns and villages in Donetsk region.
On Wednesday, Ukraine and the West have accused Russia of launching a new incursion into Ukraine by sending its troops and hardware in the Donetsk region. Russia has denied the charges.
