MOSCOW, March 23 (Reuters) - Russia's Saratov oil

refinery was hit by a drone on March 21 and the crude

distillation unit at the refinery has been shut down since the

attack, sources with knowledge of the situation told Reuters.

Ukraine's military said on Saturday it had hit the Rosneft

refinery. Saratov Governor Roman Busargin said that

civilian infrastructure had been hit but did not give details.

According to Reuters sources, the refinery's sole crude

distillation unit, which has a capacity of 20,000 tonnes per

day, has been shut down since March 21.

Rosneft did not respond to a request for comment.

During a trading session at the St Petersburg International

Mercantile Exchange on Monday, there were no offers for

petroleum products from the Saratov refinery.

In 2024, the Saratov refinery processed 5.8 million tons of

oil, which accounted for 2.2% of the total oil refining of

Russia. It also produced 1.2 million tons of gasoline, 1.9

million tons of diesel fuel and 1.0 million tons of fuel oil in

2024.
