Russia takes advantage of Ukraine's anti-aircraft weakness to launch another offensive against its energy network. The almost daily bombings have coincided with the campaign of Ukrainian attacks against the Russian oil industry.

Russia would have lost 10% of its oil refining capacity, according to British intelligence services. The last blow, on March 23 against a plant in the city of Samara, occurred just one day after Washington's first warning to kyiv.. The second offensive against the Ukrainian energy sector has coincided in time with kyv's pressure on the oil refineries.
