According to the Ukrainian Defense Ministry, Russia has more than 127,000 soldiers in the border region.
The Ukrainian intelligence report claims that Russia is "trying to divide and weaken the European Union and NATO."
Both the bloc and the body have been clear in warning President Vladimir Putin that there would be consequences if he invades Ukraine.
Amid the tensions, Antony Blinken and his Russian counterpart agreed to meet in Geneva after the Secretary of State's meetings in Kyiv and Berlin.
