As Russia continues its aerial bombardment of Ukraine with drones and missiles, Ukraine has been successfully targeting the sources of some of those attacks.

One of those was at Engels-2 Airbase, deep inside Russia and which is a key base for Moscow's strategic bombers and also serves as a refuelling point.

Engels-2, says Ukraine, also stores weapons including Kh-101 subsonic, air-launched cruise missiles, which, costing millions of dollars per missile, have been frequently used in overnight strikes.

A drone strike on Engels is reported to have destroyed ammunition storage facilities, with before-and-after images from Maxar satellite imagery detailing the extent of the operation.

Andriy Kovalenko wrote on Telegram: "At Engels, the Russians lost missiles, including the Kh-101, as a result of the strike. The number will be clear later. This airfield stores the largest number of missiles used by strategic aviation to strike Ukraine."

While Russia's military operation is defined by the sheer size of attacks, Ukraine's much more limited resources are having to be focused on pinpoint hits on key military installations.

Russia will try to continue its overnight raids to overwhelm air defences and the electronic warfare systems Kyiv uses to try to defeat the drones that pour in.
