Nato's deputy chief says Russian leaders are less and less able to conceal the deaths of "large numbers" of Russian soldiers in eastern Ukraine.
Alexander Vershbow said Russia's involvement was becoming more unpopular with the Russian public as a result.
Russian officials dismissed on Thursday a US claim that Moscow had sent "thousands and thousands" of troops to fight alongside separatists.
A foreign ministry spokesman said the figures were "plucked out of the air".
Ukraine and the West have long accused Russia of helping the rebels with weapons and soldiers,
Independent experts echo that accusation but Moscow denies it, insisting that any Russians serving with the rebels are "volunteers".
Alexander Vershbow, Nato's deputy secretary general, told a conference in Latvia: "Russian leaders are less and less able to conceal the fact that Russian soldiers are fighting - and dying - in large numbers in eastern Ukraine."
There was "mounting evidence that the Russian incursion into Ukraine is becoming much less popular among the Russian public", he added.
Earlier this week, Russian investigative newspaper Novaya Gazeta, external published an interview with a wounded tank gunner, who said that he was a regular Russian army soldier and had been fighting alongside rebels.
He said he had received thorough training in Russia before being sent to Ukraine.
Ukraine says its troops are withdrawing heavy weapons from the front line
Earlier, Ukraine's parliament passed a new law to increase the size of the country's armed forces to counter the threat from pro-Russian separatists in the east.
The bill calls for a force of 250,000 personnel, including 204,000 active troops - up from 184,000. It will now go to President Petro Poroshenko, who proposed the measure, to be signed into law.
Lull in fighting
Meanwhile the government said its army had begun the second stage of pulling back heavy weapons on Thursday in line with the ceasefire agreed in Minsk last month.
A lull in fighting has led to hopes that the truce may broadly be holding.
Ukrainian military spokesman Vladislav Seleznyov said on Thursday one soldier had been killed on the frontline in the past day.
Rebels battled government troops in the village of Shyrokyne, east of Mariupol, in the early hours, Ukrainian interior ministry adviser Zoryan Shkiryak said. But he added that there had been no other serious fighting in the area.
Both Ukraine and the rebels say they are withdrawing heavy weapons from the front line, one of the requirements of the ceasefire deal made in the Belarusian capital.
Monitors from the OSCE security group have reported weapons movements on both sides but say it is too early to confirm a full withdrawal.
