MOSCOW, Oct 29 (Reuters) - Ukraine targetted Russian

energy infrastructure with drones, disrupting air traffic across

the country and sending several drones towards Moscow for the

third straight night, Russian authorities said on Wednesday.

Russian air defence units destroyed a total of 100 Ukrainian

drones overnight, including six over the Moscow region, and the

rest over 11 regions and Crimea, the Russian defence ministry

said on the Telegram messaging app.

Kyiv has kept up long-range drone strikes on Moscow and

other Russian regions in recent months, saying the aim is to hit

energy, military and industrial assets, sap Russia's war

economy and show Russians the conflict is no longer distant.

A storage container containing fuel and lubricants in

the city of Simferopol in Russian-annexed Crimea was

hit by a Ukrainian drone

and caught fire, the Moscow-installed governor said on the

Telegram messaging app.

There were no casualties and emergency services were

working at the scene, the governor, Sergei Aksyonov, wrote on

Telegram.

Russian aviation watchdog Rosaviatsiya said three of

Moscow's four airports, and several others throughout the

country, were closed at some point in the night for safety

reasons.

In the Republic of Mari El, in the eastern part of European

Russia and about 800 kilometres (497 miles) from Moscow, strikes

were recorded near one of the region's industrial facilities,

regional authorities said, adding there was no destruction.

South of Mari El, in the Ulyanovsk region, a short-lived

fire broke out at a site of destroyed drones, the region's

governor, Alexei Russkikh, said on Telegram. It was not

immediately clear what was targeted there. Unofficial news

Telegram channels reported that Kyiv tried to hit oil

infrastructure there.

Ukraine also launched several drones targeting the

Budyonnovsk industrial zone in Russia's Stavropol region, the

region's governor, Vladimir Vladimirov, said on Telegram. The

Russian defence ministry said its units downed two drones over

the region, located in the country's south.

The attack caused no "significant" damage, and there were no

casualties, Vladimirov said on the Telegram messaging app.

According to Ukrainian media, including the RBK-Ukraine

media outlet, Kyiv attacked the Stavrolen chemical plant in the

Budyonnovsk zone, a part of Russia's Lukoil group.

According to Russian and Ukrainian media, Stavrolen is one

of Russia's main producers of polyethylene and polypropylene.

Reuters could not independently verify the reports of the

attack on Stavrolen. Stavropol's governor did not disclose what

was attacked in Budyonnovsk.

Russia typically gives limited details about the effects of

Ukrainian strikes on its territory unless civilians or civilian

infrastructure are hit.

Over the previous two nights, Russia's units destroyed 35

Ukrainian drones over the Moscow region, the Russian defence

ministry said. There was no damage reported.
