New video footage has emerged from the eastern Ukrainian city of Donetsk which purports to show US private mercenaries running through the city center.
Videos uploaded online on Friday show men dressed in US-style military outfits running through the Russian-speaking city with guns and bullet proof body-gear.
The videos also show the men being chased by the residents, with locals shouting Black Water.
That’s the name of the US mercenary company based in Virginia.
One Russian diplomat in Kiev said that 300 employees of private security companies had arrived in the country.
Donetsk was the scene of unrest this week as pro-Russian residents seized control of the regional administration headquarters.
