Ukraine's president called an emergency meeting of the nation's security council and canceled a foreign trip Thursday, declaring that 'Russian forces have entered Ukraine,' as concerns grew about the opening of a new front in the conflict, AP reported.
President Petro Poroshenko summoned the council as the strategic southeastern Ukraine town of Novoazovsk appeared firmly under the control of Russia-backed separatists.
'Today the president's place is in Kiev,' Poroshenko said.
