Fire at oil depot in Russia's Bryansk, near Ukraine

STORY: In a statement, the ministry said the fire took place at a facility owned by oil pipeline company Transneft at 2 a.m. Moscow time, and there had been no need to evacuate any parts of the city of 400,000 people.

Russia's investigative committee said in a separate statement that its head, Alexander Bastrykin, has ordered a probe into the incident. Ukrainian officials have so far made no comment on the fire and its possible cause.

Bryansk is an administrative center 154 km (96 miles) northeast of the Ukrainian border, near the Sumy and Chernihiv regions, and is about 380 km (236 miles) distant from Moscow, the Russian capital.

Moscow calls its actions in Ukraine, now entering their third month, a special military operation.
