(CNN) Russia’s Defense Ministry made the accusation on Tuesday Ukraine Russia has attempted to launch drone strikes targeting infrastructure deep inside Russia near the capital after authorities abruptly closed the airspace above the country’s second-largest city after a fire at an oil depot.
Moscow Region Governor Andrey Vorobyov said the Ukrainian drone crashed near the village of Kubastovo, southeast of the capital. The drone was targeting what he called “civilian infrastructure”, later confirmed to be a gas facility operated by state-owned company Gazprom.
The facility was undamaged, state media reported, citing the region’s energy ministry.
State media later released photos of what it said was a malfunctioning device that appeared to be a Ukrainian-made UJ-22 attack drone.
The UJ-22 is relatively small and versatile, able to fly through bad weather and travel up to 500 miles (800 kilometers). It is not clear when or where the photo of the crashed drone was taken.
The crash was said to be one of several attempted attacks, with state media reporting that a drone had been shot down near the border with Belarus and two other attacks foiled by the Defense Ministry using drone-jamming technology in the Krasnodar and Adygea regions.
“Both drones lost control and deviated from their flight path,” the Defense Ministry said in a statement. “One UAV (unmanned aerial vehicle) fell in a field, while another UAV veered off course and did not harm the civilian infrastructure that was hit.”
At least one drone appeared to have evaded Russian security, with footage posted on social media overnight by CNN showing a fire at energy company Rosneft’s oil depot in Tuaps, on the Black Sea coast of Krasnodar.
It is not clear if the facility was the intended target, but Ukraine is Previously targeted oil depots Within the territory of Russian control.
CNN could not independently confirm the claims of each attack, and Ukraine did not immediately comment on the incident. Ukraine has refused to comment on attacks inside Russia.
Following the alleged attacks, Russia’s second-largest city, St. Petersburg, closed a 200-kilometer (124-mile) radius of its airspace on Tuesday, briefly banning incoming flights, according to state media.
Russian President Vladimir Putin was informed of the closures — but Kremlin spokesman Dmitry Peskov declined to discuss whether they were related to the “incidents in St. Petersburg and Duapse,” state media reported.
Attacks targeting Russian infrastructure have focused on Ukraine’s efforts to develop long-range combat drones.
In early December, Russia announced Several attacks by Ukrainian drones Targeting military infrastructure, including air bases located hundreds of miles inside Russian territory and beyond Ukraine’s border Announced as an arsenal of drones.
At the same time, Ukraine’s state-owned arms manufacturer Ukroboronprom indicated that it was close to completing work on a new long-range drone — no public indication that such a device was ready for deployment or involved in explosions. Russia.
At the time, Ukraine’s Defense Ministry did not comment on the strikes — a presidential adviser tweeted hinting at the possibility that Kiev was indeed behind the December attack.
“The Earth is spherical — discovered by Galileo. Astronomy was not studied in the Kremlin, court astrologers were given priority. If it was, they would know: if something is launched into the airspace of other countries, sooner or later unidentified flying objects return to the place of departure,” he said then.
