Russia claims to have killed Ukrainian soldiers with "vacuum bomb"

MOSCOW: The Russian army has claimed to have killed a large number of Ukrainian soldiers with a so-called "vacuum bomb", a powerful munition that pulls out oxygen from the surrounding area to sustain an explosion, CNN reported on Saturday.

According to the CNN report, the Deputy Chief of the General Staff of the Russian Armed Forces told Russian Defence Minister Seigei Shoigu during a meeting that up to 300 soldiers were killed "as a result of an accurate strike by an aerial munition," Russia's Defense Ministry said on Saturday.

Meanwhile, Ukraine has not verified the claims of Russia. Colonel General Alexei Kim did not indicate where the strike took place but described the location of the strike as the "deployment point of the 'Kraken' nationalist formation," according to the ministry, referring to a special unit of the Ukrainian Defence Intelligence.

Kim said a "volumetric detonation bomb" was used in the airstrike, CNN reported quoting the Russian news agency, RIA Novosti.

Volumetric weapons are also known as vacuum bombs, thermobaric weapons or fuel-air explosives. The destruction caused by a thermobaric weapon is caused by the blast wave it creates and also the vacuum resulting from the fuel-air mixture sucking in oxygen to sustain the detonation, according to the Lieber Institute for Law & Warfare at the US Military Academy at West Point, New York.

The force of such a blast is enough to collapse buildings and rupture organs. Walls or even caves don't provide protection, according to the Center for Arms Control and Non-Proliferation.

Details of the Russian airstrike emerged during a meeting at the headquarters of the Joint Group of Forces, where Shoigu heard reports from commanders on the current situation in the "zone of the special military operation," the ministry said, Russia's phrase for its war in Ukraine, CNN reported.

Kim also did not mention when the strike was carried out but noted that "over the past week alone, as a result of effective work of reconnaissance and strike systems, three American Patriot complexes, a Vampire multiple rocket launcher, more than 10 foreign-made artillery systems and fuel and ammunition depots were destroyed," according to the ministry.

Kim also told Shoigu during the meeting that Ukraine is "suffering significant losses in both equipment and manpower as a result of the use of high-precision weapons and strike drones," the ministry said.
