The Security Service of Ukraine (SBU) on Tuesday claimed to have conducted a new attack on Russia's Kerch Strait Bridge -- which links occupied Crimea to Russia's Krasnodar Krai region -- two days after the service's dramatic drone strikes on Russia's strategic bomber fleet. The SBU posted a video, photograph and statement to its official Telegram channel detailing the operation, which it said "lasted several months." "SBU agents mined the supports of this illegal facility," the statement read.
