In recent days the war in Ukraine has revolved around the salt-mining town of Soledar in the east of the country.
Russia claimed on Friday that it had seized the town. The founder of the paramilitary Wagner Group, Yevgeny Prigozhin, claimed earlier this week that his troops had achieved the rare victory without any involvement from Russia's official military and pictures emerged of him and his troops inside the Soledar's famous salt mines.
Russia's defense ministry later credited the group with leading the attack after days of public sparring in a surprising concession.
Meanwhile, Kyiv has denied that Russia has taken full control of Soledar.
Officials in the US have speculated that Russia, particularly the Wagner Group, has aimed to capture the town to gain control of its valuable salt and gypsum resources for financial purposes.
Before the war the mined galleries of salt, had been convertor into a magical buried world.
