The Ukrainian military said on Thursday it had struck an ammunition depot overnight at an airfield in Russia's Adygeya region in the North Caucasus, about 450 km (280 miles) from the frontline in eastern Ukraine. Some 57 Russian combat and training aircraft and helicopters, including Su-34s, Su-35s and Mi-8s, were stationed at Khanskaya airfield during the drone attack, a source in Ukraine’s state security service (SBU) told Reuters. "Russia is using this airfield in Krasnodar Krai ... for refueling and missile and bomb attacks on the units of the Defence Forces and Ukrainian settlements," the source said.
