KYIV, May 13 — Drones launched by the Security Service of Ukraine (SBU) caused fires at an oil depot and power substation in Russia’s Belgorod and Lipetsk regions, a Ukrainian intelligence source told Reuters today.

The attack damaged "Oskolneftesnab” oil depot near the city of Staryi Oskol in Russia’s Belgorod region and "Yeletskaya” power substation in the Lipetsk region.

"Russian industry which works to wage war with Ukraine will remain a legitimate target for the SBU. Measures to undermine the enemy’s military potential will continue,” the intelligence source said. — Reuters
