Russia’s military on Tuesday said it would retaliate against Ukraine after Kyiv attacked Russian regions by firing six US-made ATACMS ballistic missiles, six UK-made Storm Shadow cruise missiles and launching one of the biggest drone attacks to date.

The barrage appeared to be one of the largest recent assaults in Ukraine’s campaign to damage Russia’s war machine on its home territory.

Ukraine claimed Saturday to have struck one of Russia’s largest oil refineries in a drone attack, starting a fire at the facility more than 700 miles into Russian territory.

Ukrainian forces used missiles and drones on Tuesday to target sensitive military and energy sites across Russia.

Ukraine carried out one of its largest drone attacks against Russia in this war, striking energy production facilities, weapons storage sites, and other military targets in about a dozen regions across the country,

Russians launched 55 Shahed attack drones and various types of imitators against Ukraine. Ukrainian air defense managed to destroy 34 of them, according to the Air Force of the Armed Forces of Ukraine.
