Russia downed four drones headed for Moscow, mayor says, after Kyiv targeted oil complex

MOSCOW (Reuters) -Russian air defences repelled an attack by four drones flying towards Moscow, Mayor Sergei Sobyanin said on Friday, with no injuries reported in the capital or in an earlier attack on an oil complex in one of Russia's southern regions.

"Emergency services are working at the site where debris came down," Sobyanin said on his official channel on the Telegram messaging app.

Sobyanin did not mention Ukraine, but Kyiv has launched a steady stream of drone attacks on Russia since President Vladimir Putin sent tens of thousands of troops into Ukraine more than three years ago, most of them targeting energy and other infrastructure.

Veniamin Kondratiev, the governor of Russia's southern Krasnodar region, said earlier that a Ukrainian attack had set a gasoline tank ablaze at the Tuapse oil complex on the shores of the Black Sea. Nobody had been hurt in the attack, he said.

As many as 121 firefighters were battling to put out the flames, Kondratiev said, without saying if the site had been hit by a drone or a missile.

The export-oriented Tuapse refinery, with a processing capacity of 240,000 barrels per day, produces naphtha, fuel oil, vacuum gasoil and high-sulphur diesel, mainly supplying China, Malaysia, Singapore and Turkey.

Andrei Vorobyov, governor of the wider Moscow region, said three of the drones heading for Moscow had been brought down over his region. Debris had fallen on a construction site and a residential building under construction, he said.

One of the drones had hit the roof of a multi-storey residential building in the west of Moscow, the RIA news agency reported, citing information from emergency services.

The TASS news agency reported that debris had also fallen on a private house on the outskirts of Moscow.
