A section of the Kerch Bridge, which connects Russia to Crimea, was blown up, killing two people and disrupting traffic, AP News reports.
The strike was carried out by two Ukrainian sea drones, according to Russia’s National Anti-Terrorist Committee.
Ukrainian officials did not explicitly claim responsibility, but a spokesman for the Ukrainian Security Service hinted at their involvement.
This marks the second major attack on the bridge, following a truck bomb incident in October.
