The Security Service of Ukraine (SBU) carried out the third attack against the Crimean Bridge since Russia's full-scale war began in 2022, mining and damaging its underwater supports, the SBU announced on June 3.
"God loves the Trinity, and the SBU always brings what is conceived to the end and never repeats itself," SBU Chief Vasyl Malyuk said in a statement posted on social media.
"Previously, we struck the Crimean Bridge in 2022 and 2023. So today we continued this tradition underwater," he added.
The SBU said the operation "lasted for several months," with agents mining the "supports of this illegal construction."
Constructed after Russia’s illegal occupation of Crimea in 2014, the Crimean Bridge is a critical supply and transport route for Russian forces to the occupied Ukrainian territories.
"And today, without inflicting any civilian casualties, the first explosive was activated at 4:44 a.m.," the SBU said.
Underwater supports of the bridge's piers were severely damaged at the bottom as 1,100 kilograms of explosives in TNT equivalent were detonated, according to the statement.
Russian state media later reported a "Ukrainian intelligence agent" who had constructed a bomb on "orders from Kyiv" had been detained by Russia's FSB.
In comments later on June 3, Dmytro Pletenchuk, a spokesperson for the Ukrainian Navy, said the "key and most complex" part of the bridge had been damaged in the attack.
The operation, which follows the SBU's mass drone strike against Russia's strategic aviation on June 1, was personally supervised by the agency's chief, Vasyl Maliuk.
President Volodymyr Zelensky praised the SBU in his evening address, though he did not refer to the attack directly.
"And it is always nice to give special thanks to the Security Service of Ukraine, well done!" he said.
A claimed "agent of Ukrainian intelligence services" has been detained in Crimea, Russia's Federal Security Service said later on June 3, accusing the detainee of producing a "powerful explosive."
The bridge suffered significant damage during two previous Ukrainian attacks in October 2022 and July 2023, though neither managed to take the bridge out of commission.
The construction of the bridge, also known as the Kerch Bridge, holds a significant symbolic value for Russia. The $4 billion project was a political statement designed to affirm the Kremlin's illegal 2014 annexation of Crimea, as the peninsula is not connected by land to Russia.
Russia's Defense Ministry previously claimed that three Ukrainian drones were downed over Crimea overnight on June 3.
The Crimean Bridge was closed for traffic between 6 and 9 a.m. local time on that day, according to local Telegram channels. The Mash Telegram channel reported that a Ukrainian drone was shot down over the bridge, and its debris fell onto the road.
According to pro-Ukrainian Telegram channel Crimean Wind, the bridge had been closed down for inspection, possibly to examine damage.
Later the same day, Crimean Wind reported a new "powerful explosion" near Kerch at around 3 p.m., writing that a helicopter is patrolling the strait. Several local channels reported that a fresh drone attack against the peninsula was underway in the afternoon, and that the bridge is closed once again.
The Kyiv Independent could not verify the claims.
