The British Ministry of Defence (MoD) confirmed on Wednesday that the Russian military shot down one of its own Sukhoi Su-35S (NATO reporting name Flanker M) multi-role combat jets over the Ukrainian city of Tokmak in the Zaporizhzhia region last Thursday.

The incident occurred about 20km (12.5 miles) from the current front lines.

It is reported to be the fifth loss of a Su-35S, which is the Kremlin’s most advanced combat jet in widespread service. Russia has lost around 90 fixed wing aircraft since the start of the war.

“The location is relevant because Tokmak is a heavily fortified town which often hosts Russian headquarters commanding one of the most intensely contested sectors of the front line,” the MoD announced via its recent intelligence update posted on X, the social media platform formerly known as Twitter.
