On 4 July, Russia said five drones were used in an attack which targeted locations in the wider region around the capital. Oil facilities, airfields and energy infrastructure have all been targeted. Flights were forced to be diverted from Vnukovo International Airport in Moscow after a drone attack on 4 July. These have mostly been in the Bryansk and Belgorod regions in Russia near the north-eastern border with Ukraine, as well as in Russian-annexed Crimea. Is this a revenge or a terrorist attack ?
