MOSCOW (Reuters) -Russian air defences repelled an attack by four drones flying towards Moscow, Mayor Sergei Sobyanin said on Friday, with no injuries reported in the capital or in an earlier attack on an oil complex in one of Russia's southern regions.

The Ministry of Emergency Situations of Russia has issued instructions according to which civilians "in no case should", in particular, "shoot down drones with improvised objects and other means," as well as use "radio equipment and mobile phones and GPS devices near the drone.

Three men have been killed in the Moscow region, in what is described as the largest drone attack on the Russian capital since the start of the full-scale war in Ukraine. A further 18 people, including three children, were injured, health officials told Russian media.

A third person has died as a result of a Ukrainian drone attack on the Moscow region, Evgeniya Khrustaleva, the head of the town of Domodedovo, said on Tuesday via her channel in Telegram.

The assault, which the mayor called the largest on Russia’s capital since the war began, was a reminder of Ukraine’s power to strike as its president proposes an air truce.

Ukraine on Tuesday launched its biggest ever drone attack on Moscow and the surrounding region, killing at least three employees of a meat warehouse, injuring 17 others and causing a short shutdown at the Russian capital's four airports,
