UKRAINE has reportedly downed another Russian fighter jet – the third in just three days.

The Air Force of Ukraine’s Armed Forces claimed today that the Su-34 fighter-bomber was struck in the “eastern direction”.

The air force wrote on Telegram: “Today, February 29, is a date that occurs once every four years, but it is already a familiar day for Russians with the loss of another plane.

“Minus Su-34 in the Eastern direction! Thanks for the work!”

Yesterday, Ukraine’s air force claimed to have destroyed two of the Russian jets in a single day.

The alleged attack comes during amid a hellish time for Vladimir Putin, who before today had already lost $870million (£687million) worth of Russian war planes in just 10 days.

It brings the total number of Russian planes shot out of the sky by Ukrainian armed forces to 11 – in just two weeks.

On Tuesday morning, Ukraine downed a Russian Su-34 fighter-bomber on the eastern front.

Another Su-34 aircraft was shot out of the sky that same afternoon.

Each Su-34 blitzed is estimated to be worth about $50million (£39million), meaning Putin has now lost some $920million (£727million) worth of war planes in a matter of days.

The feared aircrafts are the Russian air force’s top strike planes and their continued destruction marks a devastating setback for Putin.

Before Tuesday, another eight war planes were obliterated by Ukraine in just 10 days following a number of successful strikes.

Six of the planes struck were Russia’s beloved Su-34s, and the other two were Sukhoi Su-35s, with a combined value of $170million (£134million).
