According to the Ukrainian Ministry of Security (SBU), a massive underwater explosion against a bridge connecting Russia to Crimea put it on Tuesday with a “state of emergency”.

The surprising explosion came days after Ukraine's "Spider-Man's Network" which was a series of coordinated drone attacks that penetrated Russian territory, believed to have occupied dozens of Russia's most powerful bomb-firing and surveillance planes while they were believed to have been idle at five military airports.

"Illegal objects of the Russian Federation have no status on the territory of our state. Therefore, the Crimea Bridge is an absolutely legitimate target, especially given the enemy's use of it as a logistical artery to secure its troops," Lieutenant General SBU said in a statement. "Crimea is Ukraine and any performance of the occupation will be answered harshly by us."

SBU said it detonated about 2,500 pounds of underwater explosives along the coast of the Kexi Bridge. Video shows the explosion surrounding one of the bridge pillars, and then an investigation into those who caused damage on the bridge.

The bridge was reportedly reopened before its second closure.

SBU said no civilians were injured in the explosion.

“Previously, we hit the Crimean Bridge twice in 2022 and 2023. So today we continue this tradition already underwater.”
