Ukraine's defence forces struck the Saratov oil refinery, the Engels airfield, a fuel depot in Kaluga Oblast and a number of other Russian military facilities on the night of 1-2 August.

Russia stores its Tu-95 and Tu-160 bomber aircraft at the Engels-2 base and uses these planes to carry out strikes against Ukraine.

Drone and missile alerts were issued in Russia's Engels overnight July 25 as a major fire reportedly broke out at a military site, while another large blaze erupted in Rostov, Astra reported on July 25.

Two people have been killed in Russia as a result of Ukrainian drone attacks. Civilian infrastructure in Saratov and Engels was damaged, wrote Roman Bussargin, governor of the Saratov region, on Telegram,

Kyiv's depleted air defences meant many of the missiles were not intercepted - like the one that hit Anastasiia's home.

Ukraine’s Defense Forces struck Russia’s Engels air base, the Saratov oil refinery and an oil depot in Kaluga Oblast overnight on Aug. 2, Ukraine’s General Staff said.

Ukraine has requested more air defences from its allies after a Russian strike killed more than a dozen people.

When Russia fires a ballistic missile at Ukraine, air-defense systems have only minutes — sometimes seconds — to detect and intercept the deadly threat.
