Ukraine and Russia have been exchanging major drone and missile strikes, with each seeking to gain an advantage as US President-elect Donald Trump’s inauguration nears

Russia's military on Tuesday said it would retaliate against Ukraine after Kyiv attacked Russian regions by firing six U.S.-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.

Ukrainian officials say Russia has launched a major ballistic and cruise missile attack on regions across Ukraine.

Russia launched a new barrage of missiles and drones at Ukraine on Wednesday, targeting gas infrastructure and other energy facilities in western regions in the latest strike on the country's hobbled power system as it approaches mid-winter.

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.

Russia launched dozens of missiles and drones at the Ukrainian energy sector, Kyiv said Wednesday, ramping up a months-long bombing campaign at a precarious moment of the war for Ukraine.The barrage came just one day after Kyiv said it had carried out its largest aerial attack of the war on Russian army factories and energy hubs hundreds of kilometres from the front line.

Russian troops pressing their slow advance through eastern Ukraine took control of two settlements in Donetsk region, Russia's Defence Ministry said on Tuesday.

Nikolai Patrushev, an advisor to the Russian president, stated in an interview with "Komsomolskaya Pravda" that the Russian Federation is not indifferent to what is happening in Ukraine. However, he did not rule out the possibility that Ukraine may cease to exist altogether next year.
