A building for the border patrol of Russia’s Federal Security Service, or FSB, exploded in flames on Thursday in the southern city of Rostov-on-Don, killing at least one person and injuring at least two, according to Russian media and local officials.
The governor of the Rostov region, Vassily Golubev, writing on Telegram, said the fire had spread over 800 square meters — roughly 9,000 square feet — causing two walls to collapse. Residents of surrounding buildings were evacuated and at least one person was hospitalized with serious injuries, Golubev said.
The FSB is Russia’s main domestic security service, responsible for border security, surveillance and counterterrorism.
In recent weeks, amid a rising number of cross-border attacks from Ukraine, including drone strikes, President Vladimir Putin has ordered officials to tighten security in Russia’s border regions, including Kursk, Bryansk, Belgorod and Rostov.
Local residents told Russian media outlets that they heard loud explosions before the fire broke out.
Golubev and local emergency services officials said on Thursday that a short circuit sparked the blaze, by igniting fuel tanks. The Washington Post could not independently verify these reports.
Citing local emergency officials, Tass, the state-controlled news service, reported that as a result of the fire, one person had died and at least two more were injured.
The FSB, however, later issued a statement giving a slightly different cause of the fire. “Fuel and lubricants caught fire in a maintenance shop of the garage of the staff of Russia’s FSB border department in the Rostov region at 12:20 p.m., causing an explosion and partial collapse of the building,” the security service said, according to the Interfax news service.
In Russia’s border regions, there is rising concern about sabotage by groups opposed to Russia’s invasion of Ukraine, and growing anxiety after a flurry of drone sightings in Western Russia and an attack in Bryansk claimed by a rogue Russian nationalist group.
“It is necessary to keep the Russian-Ukrainian border under special control, to put a barrier for sabotage groups there,” Putin said at a board meeting of the FSB in late February. “The FSB must respond to the intensification of Western intelligence activities against Russia.”
Mykhailo Podolyak, an adviser to Ukrainian President Volodymyr Zelensky, said that the fire suggested further internal turmoil in Russia. “Any FSB building that burns or explodes in [Russia], particularly in Rostov region, clearly indicates that this is a manifestation of panic, weakening of power control and [Russia’s] transition to a major internal conflict,” Podolyak tweeted.
“Ukraine doesn’t interfere,” he added, “but watches with pleasure.”

War in Ukraine: What you need to know
The latest: The Kakhovka dam and hydroelectric power plant in southern Ukraine were severely damaged on May 6, unleashing flooding near the front lines. Ukraine and Russia each blamed the other for attacking the site, destroying the plant and damaging the dam. As water gushed from the facility on the Dnieper River, which separates Ukrainian and Russian forces, officials on both sides ordered residents to evacuate.
The fight: Russia took control of Bakhmut in eastern Ukraine, where thousands of Russian and Ukrainian soldiers died in the war’s longest and bloodiest battle, in late May. But holding the city will be difficult. The Wagner Group, responsible for the fight and victory in Bakhmut, is allegedly leaving and being replaced by the Russian army.
The upcoming counteroffensive: After a rainy few months left the ground muddy, sticky and unsuitable for heavy vehicles in southern Ukraine, temperatures are rising — and with them, the expectations of a long-awaited counteroffensive against occupying Russian forces.
The frontline: The Washington Post has mapped out the 600-mile front line between Ukrainian and Russian forces.
