Two drones damaged an administration building of an oil pipeline in Russia's western Pskov region, the regional governor said Saturday.
The explosion is the latest in an escalating series of attacks in Russia amid the Ukraine offensive.
"Early morning, an explosion damaged the administrative building of the oil pipeline near Litvinovo, Nevelsky district," governor Mikhail Vedernikov said.
Shortly after, he said that, according to preliminary information, the building was "damaged as a result of an attack by two unmanned aerial vehicles."
There were no reported casualties, and an investigation was still ongoing.
Unconfirmed reports from Baza, a Russian Telegram outlet with sources in the secret services, said the drones were targeting the Transneft oil pumping station in Pskov.
The blast took place in the village of Litvinovo, around 10 kilometres (6.2 miles) from the Belarusian border.
Over the past few weeks, reports of drone attacks in Russia have multiplied, usually in regions bordering Ukraine.
On Friday, two drones damaged buildings in the centre of the southern Russian city of Krasnodar, which had been relatively unaffected.
Moscow has blamed Kyiv -- and its Western supporters -- for the escalating number of attacks and sabotage operations, including on the Kremlin.
Ukraine has denied involvement.
