Nato has seen Russian military equipment and Russian combat troops entering Ukraine this week, its top commander Gen Philip Breedlove says.
Nato chief Jens Stoltenberg later urged Russia to pull back its forces.
Russia's defence ministry denied sending troops to eastern Ukraine to help pro-Russian separatists there.
