A major explosive factory deep inside Russia which supplies Vladimir Putin ’s army was attacked, says Ukraine. The plant is in the Tambov region hundreds of miles from the border with Ukraine.

Russia launched a large-scale missile attack on Wednesday, some slamming into energy facilities that caused power losses in several regions of the country, officials said.

The Russian missiles sought out targets from the Lviv region in western Ukraine near Poland to Kharkiv in northeast Ukraine bordering Russia. The state energy company Ukrenergo reported emergency power outages in six regions. It often shuts down production during attacks as a precaution.

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.

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.

Sen. Marco Rubio used his confirmation hearing Wednesday to warn a Senate panel that China might move against Taiwan before the decade is over and that a potential ceasefire agreement between Russia and Ukraine must provide the Ukrainians with sufficient leverage to deter a repeat invasion in the future.
