Ukraine's largest strike on Moscow hits the capital's main refinery on election day
The Kyiv Independent (https://kyivindependent.com/russia-says-dozens-of-ukrainian-drones-targeted-moscow-as-broader-attack-hit-multiple-regions/) reports that overnight into 20 September, the final day of Russia's Duma vote, Ukraine struck the Gazpromneft Moscow Oil Refinery. The AVT-6 primary distillation unit, the integrated refining unit and the isomerisation unit were damaged. The plant supplies about 40% of Moscow's fuel. Mayor Sobyanin said more than 1,600 drones were downed across Russia, 450 of them aimed at Moscow. Two people were killed, and Domodedovo and Zhukovsky airports were restricted. Zelensky called it Ukraine's largest-ever attack on the capital. Totals from Russian officials vary between reports.
Interpretation: Kyiv is showing that its long-range campaign can reach the most protected market in Russia and can be timed for political effect. The pressure point is economic: the Bank of Russia already blamed refinery strikes for holding rates at 14% on 11 September (Moscow Times). The strike also gives Ukraine a bargaining chip. Halting refinery strikes is the obvious Ukrainian concession in any energy-infrastructure truce, so Moscow now has a sharper incentive to consider one, or to escalate against Ukraine's grid before winter.
