A Ukrainian sea drone has destroyed a Russian helicopter off the coast of Crimea for the first time. Footage of the attack shared by HUR, Kyiv’s military intelligence, showed the drone bobbing on the seas as the aircraft manoeuvred in the skies above. Plumes of water splashed up next to the Magura V5 drone as Russian fire hit the sea around it.

Ukraine’s intelligence service said a naval drone had struck down a Russian military helicopter for the first time and forced another one to return to an airfield after being hit.

At least six people were injured in Kyiv as Russia launched a drone strike on the capital in the early hours of Wednesday, city officials said.

Russia launched a drone strike on the Ukrainian capital Kyiv early on Wednesday, wounding at least six people and damaging buildings in two districts, city officials said. Explosions boomed across the morning sky as Ukraine's air force warned of drones approaching the city and Mayor Vitali Klitschko said air defences were repelling an enemy attack.

Ukraine has made history by downing a Russian helicopter with a naval drone for the first time, shifting the landscape of the war.
