Russia says Ukraine has launched a series of drone strikes on its territory in recent months, including an attack on Moscow this week. On 4 July, Russia said five drones were used in an attack which targeted locations in the wider region around the capital.
It has also accused Ukraine of trying to kill President Vladimir Putin in an alleged attack on his residence in the Kremlin on 3 May. Oil facilities, airfields and energy infrastructure have all been targeted.
Ukraine denies carrying out the attacks. We have identified at least nine reported drone attacks on oil depots. One of these was in Sevastopol, a major city in Crimea, which was hit on 29 April, destroying several of its oil tanks.

The regional governor said it was probably caused by a drone.
Another oil refinery in Krasnodar Territory, first struck earlier in May, was hit again by a drone, but no damage was caused according to Russian officials. Layla Guest, an analyst at Sibylline security consultancy, says: "Ukrainian forces will highly likely prioritise targeting oil refineries, as well as railway infrastructure and wider Russian logistics, to cause maximum disruption as part of their strategy ahead of the impending counter-offensive."
A suspected drone attack injured at least 10 Russian soldiers at a military training ground in the Voronezh Region on 10 May, according to local media reports.
