Single Ukrainian tank seen taking on entire Russian convoy close to Kyiv

This is the incredible moment a Ukrainian tank appears to destroy several Russian armoured vehicles on the outskirts of Kyiv.

The footage shot from above and shared on Telegram, appears to show a Ukrainian T-64 tank ambushing a convoy of Russian BTR-82A armoured vehicles on a road in Nova Basan - 50 miles west of Kyiv.

The operator fired several rounds at the Russian convoy and causing one BTR to alight on fire.

The other armoured vehicles then started firing back at the tank, and appeared to fire at targets not seen in the shot as streaks of fire were seen going across fields.

However, the tank pushed forward and continued shelling the Russian troops until artillery reinforcements arrived.

It comes as NATO's Secretary-General warned that Russian forces are getting ready for a “major offensive” in eastern Ukraine - and NATO needs to be “prepared for the long haul".

Opening a two-day summit of coalition foreign ministers on Wednesday, Jens Stoltenberg said talks would focus on what extra military equipment members can provide to Kyiv as Ukrainian troops battle to repel Kremlin invaders.

The war had reached a “critical phase”, said former Norwegian PM Mr Stoltenberg, as he predicted a battle for Donbas in eastern Ukraine, where Russian-backed separatists have battled Ukrainian soldiers since 2014.

“ Russia is moving forces out of the north to reinforce them, to resupply them, re-arm them and then to move them into the east where we are expecting a major offensive,” said the Secretary-General.

“Putin’s aim is to try to control the whole of Donbas.”

He said it was still the Russian leader’s ambition to “rewrite the international order”, adding: “We need to be prepared for the long haul.”

Alliance countries were playing a leading role in gathering evidence for potential prosecutions, said Mr Stotlenberg.

He added: “Any targeting and killing of civilians is a war crime and therefore NATO allies are supporting the international efforts to establish all the facts, to investigate and to make sure that perpetrators are punished.”

The possible entry of Finland and Sweden into NATO could be “quite smooth” if they applied to join the alliance, he added.
