One of Moscow's fighter jets has been shot down by Ukrainian forces, according to a military blogger with links to the Russian air force. Another pro-Moscow milblogger said that the Sukhoi Su-34 aircraft had been downed by a Western-supplied F-16.
Neither report has been confirmed and Newsweek has contacted the Russian and Ukrainian defense ministries for comment over the unverified claims which have sparked much speculation on social media.
The Telegram channel Fighterbomber posted on Saturday a message which looked like a tribute to a lost Su-34 fighter jet. Next to an image of the supersonic medium-range fighter bomber, which has been a mainstay of Russia's aviation efforts in the war it started, it said, "the earth is the sky, brothers."
