The Ukranian government has revealed its own military force as tensions increase in the Ukrainian Border that was annexed by Russian.

The Ukrainian government posted a video of troops were rehearsing.

The video also shows repel tanks and troops rehearsing near the border with Crimea, which Russia annexed in 2014.

The footage intended to instil confidence at home, and to send a message to Moscow as 1000s of Russian troops massed on Ukraine’s eastern frontier.

The drills came a day after US President Joe Biden phoned his Russian counterpart to warn him against the military buildup.

A message reiterated when the US Secretary of State Antony Blinken visited NATO in Brussels.

Fighting has increased in recent weeks in eastern Ukraine where government forces have battled Russian backed separatists in a seven year conflict.

NATO says the number of Russian troops close to the border is now the highest since 2014.
