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 launched a drone attack on a Russian chemical plant in the western city of Tula overnight on Friday into Saturday, according to the country’s security service. Russian authorities have not acknowledged the attack.
