Overview

• Two overnight blasts brought down bridges in the Bryansk and Kursk regions, derailing passenger and cargo trains on key western Russian rail lines.
• The Bryansk collapse at 22:44 local time on May 31 caused train N.86 to derail, leaving at least seven dead and around 66 wounded, including three children.
• In Kursk around 3 a.m. on June 1, a second bridge explosion sent a freight locomotive crashing onto a highway and ignited a fire that injured its crew.
• Russia’s Investigative Committee and FSB have classified the incidents as terrorism and are probing the use of explosives at both sites.
• Kyiv has issued no official response, even though past sabotage of rail infrastructure near Ukraine has occasionally drawn muted praise from Ukrainian officials.
