'KIEV (Reuters) - Ukraine accused Russia on Thursday of mounting an invasion in the southeast of the country in support of pro-Moscow separatist rebels.
Ukraine's security and defense council said the border town of Novoazovsk and other parts of Ukraine's south-east had fallen under the control of Russian forces who together with rebels were staging a counter-offensive.
"A counter-offensive by Russian troops and separatist units is continuing in south-east Ukraine," the council said in a post on Twitter.'

No idea if it is true or not.
Ukraine has become the kings of unfounded accusations lately.
So I assume it is probably not true.
