A "Ukrainian" drone has been found outside Moscow, an official has said, adding that the discovery had forced local authorities to call off a Victory Day parade for security reasons. Moscow has accused Ukraine of being behind a number of drone attacks on military infrastructure deep inside Russian territory. On Monday, Igor Sukhin, head of the Bogorodsky city district outside the capital Moscow, said that a local resident had found a "Ukrainian" drone in a forest. "This is not the first drone that appeared in the Moscow region," Sukhin said on the messaging app Telegram. A similar drone was in February found in the town of Kolomna approximately 100km (about 60 miles) southeast of Moscow, he added.
