RUSSIA has warned Britain that supplying arms to Ukraine will intensify the conflict and make them “legitimate targets.”

The charge by the country’s UK ambassador comes as Ukrainian troops use a British missile for the first time to knock a Russian helicopter out of the sky.

Following a summit of the country’s military contributors, Defence Secretary Ben Wallace stated that more weaponry will be deployed to Kyiv.

“All arms deliveries, notably those highlighted by Wallace, are destabilising,” warned Russian envoy Andrey Kelin, according to Russian news agency TASS.

“They aggravate the issue, making it bloodier.” Those appear to be new, high-precision weaponry.

“Naturally, if such supplies cross the Ukrainian border, our military forces will regard them as a lawful target.”

Mr Wallace held a gathering of 35 nations assisting Ukraine, and he stated that “more lethal aid” will be sent to the country.

He stated that Ukraine will receive longer-range artillery, and that the nations have also agreed to send anti-ship missiles.

The United Kingdom has previously delivered hundreds of anti-tank missiles to Ukraine, which have proven devastating against the Russians.

However, the ambassador stated that “bad judgments of this sort are quite harmful, because they seek to feed the conflict.”

“They show a determination to cause us as much pain as possible,” he continued.

He went on to say that giving additional weaponry will just help to reinforce the notion that “there is no need for discussions at this time.”

“This is the ostrich attitude, burying your head in the sand in a frenzy of impotence and blind wrath,” he explained.

His charges come as spectacular footage reveals the moment the Mi-28N gets hit by the Starstreak in eastern Ukraine’s Luhansk area.

The Starstreak is the fastest surface-to-air missile in the world, capable of travelling at three times the speed of sound.

According to Ministry of Defence officials, this is the first time the missile has been deployed to destroy a Russian airliner.

The helicopter can be seen in the footage skimming the treetops before being struck in the tail by the Starstreak.

The missile can be seen rising off through the treetops, heading for its target.

The back section of the chopper suddenly explodes into flames and falls to the ground as the aircraft plummets to the ground.

Other footage shows the aeroplane debris strewn across a road as Ukrainian forces assess it.

The two crew members on board the helicopter were said to have survived the shooting, however it is unknown if they were taken by the Ukrainians.

Defence sources who watched the video of the Russian helicopter’s crash think it was caused by a Starstreak.

On March 9, Britain declared that it will be supplying the Ukrainians with high-velocity portable missiles.

The Belfast-made missiles may be shoulder-mounted or connected to a vehicle, and each missile separates into three darts to breach armour before detonating warheads.

The Starstreak anti-aircraft missile is not a “fire and forget” device like other anti-aircraft missiles.

An operator on the ground guides the darts to their targets, making it impossible for the opponent to install countermeasures.

Ukrainian forces have been training with the top Starstreak operators from the United Kingdom at a secret site in a neighbouring nation.

The intense training was designed to prepare them to use the missiles in warfare over the period of two to three weeks.

Mr Wallace had stated that the Starstreak system will be operational soon.

Britain just announced that it will send additional 6,000 anti-tank missiles and explosive weaponry to Ukraine in order to “keep the torch of freedom alive.”

Boris Johnson has pledged to provide more defensive lethal help to President Volodymyr Zelensky’s military, including NLAW tank busters.

The new consignment of firearms brings Britain’s total given to Ukraine to 10,000, only days after Ukraine warned that supplies were running low.

The United Kingdom has previously sent 4,000 anti-tank artillery pieces, including Next-Generation Light Anti-Tank Weapons Systems, or NLAWs, and Javelin missiles.
