An explosion in a Russian region bordering Ukraine derailed a freight train on Monday, the local governor said in a social media post.
Pictures shared on social media showed several tank carriages laying on their side and dark grey smoke billowing into the air at the site of the derailment in the Bryansk region.
No casualties have so far been reported.
Russian Railways, the country’s rail operator, said the incident occurred at 10:17 Moscow time (0717 GMT). It said the locomotive and seven freight wagons were derailed and the locomotive caught fire.
“An unidentified explosive device went off at the 136-kilometre mark on the Bryansk-Unecha railway line, derailing a freight train,” Bryansk Governor Alexander Bogomaz said in a post on his Telegram channel.
It comes as Ukraine activated air defence systems and sounded air raid alerts across the country after Russia fired another barrage of missiles towards the besieged nation in the early hours today.
Blasts have been reported in Dnipropetrovsk and Sumy so far. Locals were seen taking shelter in metro stations after the whole country came under air raid alert.
