Russia has long said that NATO military personnel have been present in Ukraine and that its eavesdropping services have picked up English and French being spoken repeatedly at the front lines.
The U.S.-led NATO military alliance says it supports Ukraine but has not deployed soldiers there. U.S. media reports indicate that U.S. and leading European intelligence agencies have a significant presence in Ukraine.
"Our military hears foreign speech, they constantly hear foreign languages at the front," Kremlin spokesman Dmitry Peskov told reporters when asked about claims that France was preparing to deploy some soldiers to Ukraine.
"So, these foreigners are there, we are destroying them. Our military will continue to do their job."
