Russia and Ukraine have carried out their biggest drone attacks against each other since the start of the war. Russia's defence ministry also said it intercepted 70 Ukrainian drones over six regions, including some approaching Moscow which forced flights to be diverted from three of the capital's major airports.

Ukraine attacked Moscow on Sunday with at least 34 drones, the biggest drone strike on the Russian capital since the start of the war in 2022, forcing flights to be diverted from three of the city's major airports and injuring at least five people.

A United Kingdom official said Russian forces suffered their worst month of casualties since they invaded in February 2022.
