Four Russian military aircraft including two fighter jets and two military helicopters have been shot down near the Ukrainian border, according to Russian news outlet Kommersant. The raiding party was reportedly on a missile and bomb delivery mission before being ambushed in the Bryansk region that borders northeast Ukraine. A video posted on the Russian Telegram channel Voyenniy Osvedomitel, with roughly 500,000 followers, showed a helicopter exploding in flames before hitting the ground. Other images posted by the channel showed the wreckage in an agricultural field. While Russia is yet to confirm the event, emergency service officials suggested an engine fire caused a helicopter to crash near Klintsy, which is 40km away from the border. The video posted to the channel Voyenniy Osvedomitel indicates that the missile was used to shot down one of the Mi-8 helicopters which was an electronic warfare craft capable of jamming enemy radio and targeting signals. All four crews have reportedly been killed.
