Ukraine struck oil pipeline installations deep inside Russia on Saturday with a series of drone attacks including on a station serving the Druzhba pipeline, while shelling from Ukraine killed at least two, Russian officials and media said.
Ukrainian drone attacks inside Russia have been growing in intensity in recent weeks, and the New York Times reported that U.S. intelligence believes Ukraine was behind a drone attack on the Kremlin earlier this month.
Ukraine has not publicly acknowledged launching attacks against targets inside Russia. The Ukrainian defence ministry did not immediately respond to a request for comment on Saturday.
In the Tver region, which lies just northwest of Moscow, two drones attacked a station that serves the Druzhba (Friendship) pipeline, one of the world's largest oil pipelines, the Kommersant newspaper said.
The Tver local council said that a drone had crashed near the village of Erokhino, around 500 km (310 miles) from the border with Ukraine.
The Telegram channel Baza, which has good sources among Russia's security services, said the drones attacked a station serving the Druzhba pipeline.
In Russia's Belgorod region, Ukrainian shelling killed at least one person and injured three, including a 15-year-old girl and a 17-year-old boy, Vyacheslav Gladkov, the governor of the region said.
Gladkov, whose region borders Ukraine and was the target of pro-Ukrainian fighters this week, said a power line was also damaged. In Kursk region, a construction worker was killed in shelling near the border with Ukraine, the local governor said.
Druzhba, built by the Soviet Union, has capacity to pump more than 2 million barrels per day (bpd) but has been severely under-utilised as Europe sought to reduce its dependency on Russian energy after President Vladimir Putin sent troops into Ukraine last year.
Russia's oil pipeline operator Transneft said earlier this month that a filling point on Druzhba in a Russian region bordering Ukraine had been attacked.
DRONE BATTLE
At its daily briefing on the Ukraine war, Russia's defence ministry said it had destroyed 12 Ukrainian drones in the past 24 hours and intercepted two long-range Storm Shadow cruise missiles that were supplied to Ukraine by Britain.
Russia also said it had intercepted shorter-range U.S.-built HIMARS-launched and HARM missiles. The ministry did not say where those interceptions took place but reported fighting at points along the front line.
Reuters could not immediately verify battlefield accounts from either side.
Ukraine's Ministry of Defence did not immediately respond to a request for comment. Kyiv officials have previously said that Western-supplied weapons would be used exclusively against Russian forces inside Ukraine.
In the Pskov region of Western Russia, two drones caused an explosion that damaged an oil pipeline's administrative building, local Governor Mikhail Vedernikov said. The incident occurred near the village of Litvinovo, less than 10 km (6 miles) from Russia's border with Belarus.
"Provisionally, the building was damaged as a result of an attack by two unmanned aerial vehicles," Vedernikov said.
