KYIV (Reuters) -Ukraine said on Friday its drones struck a Russian fighter aircraft plant in the Moscow region and a missile production facility in the Tula region, causing explosions and fires at both. Ukraine's military said on Telegram the aviation facility in the town of Lukhovitsy, about 135 km (84 miles) southeast of Moscow, produced MiG fighters. The other site was the Instrument Design Bureau, which specialised in producing anti-aircraft missiles and missile-gun systems, it said.
