Russia has used a thermobaric bomb against Ukrainian forces as it announced a “counter-terrorism” operation to retaliate against Ukraine’s shock incursion into Kursk.
The Russian defence ministry said fighting was continuing in the western Kursk region following Ukraine’s unprecedented attack on its territory earlier this week.
The Russian army has conducted airstrikes against Ukrainian forces, including using a thermobaric bomb, also known as a vacuum bomb.
The pressure from the bomb’s extra hot blast is capable of vaporising human bodies.

It is not the first time Moscow is reported to have deployed such weapons, as Ukrainian officials alleged they were being used in the invasion just weeks after it began in February 2022.

Moscow on Saturday announced it was launching a “counter-terrorism operation” in response to the largest cross-border attack by Ukraine since Russian President Vladimir Putin ordered a full-scale invasion of his smaller neighbour.

Sky News’ security and defence analyst Professor Michael Clarke said on Friday that Ukrainian forces advanced on Kursk and “pushed in towards Sudzha, which is a logistical hub, and they’ve been fanning out, northeast and southeast from there”.
Sudzha is the last operational trans-shipping point for Russian natural gas to Europe via Ukraine.
“They’re miles deep into Russia… and that’s big – that’s not just a raid,” Professor Clarke said.
