Ukrainian army medics, bringing wounded soldiers from the nearby frontlines around Bakhmut in eastern Ukraine, welcomed news of the military rebellion in Russia.
“If there’s a revolution in Russia, I’m going to get drunk!” grinned one, in the small town of Chasiv Yar.
But others were wary about predicting what impact it might have on the war.
“I hope it helps us," said another experienced military doctor. "But I’m not sure I believe it. It seems more like some kind of show, rather than a real revolution."
With Ukraine in the middle of a key counter offensive, there's a possibility that the country will rush to take advantage of the chaos - and the likely drop in Russian troop morale.
What has been happening?
There has been a dramatic escalation of infighting between Russia's Wagner mercenary group and the Russian military.
- Wagner boss Yevgeny Prigozhin called for rebellion against the army, accusing it of carrying out a missile strike against his forces, something the defence ministry denies
- The Kremlin says Prigozhin is now being investigated for inciting mutiny
- Security has been tightened in Moscow and in the city of Rostov-on-Don, about 100km to the east of the Ukrainian border
- Prigozhin says his forces have entered Russia from Ukraine - although we have not yet seen evidence of this. He has also claimed his forces have shot down a Russian helicopter, again without providing evidence
- The governor of Russia's Rostov region has told residents to stay indoors and remain calm
- Russian president Vladimir Putin is being updated on the situation, as is US President Joe Biden
