The BBC reported:
Nato officials have seen Russian military equipment and Russian combat troops entering Ukraine this week, its top commander says.
“Russian tanks, Russian artillery, Russian air defence systems and Russian combat troops” were sighted, US Gen Philip Breedlove said.
Russia’s defence ministry denied that its troops were in eastern Ukraine to help pro-Russian separatists there.
However, the rebels have admitted being helped by “volunteers” from Russia.
The United Nations Security Council is convening an emergency session later on Wednesday to discuss the reported sightings.
Heavy artillery fire rocked the east Ukrainian city of Donetsk, the industrial hub held by pro-Russian separatist rebels, on Wednesday morning.
