Ukraine’s Security Service (SBU) confirmed it damaged the Crimea Bridge on Tuesday using underwater explosives equivalent to 1,100kg of TNT. The operation, led by SBU chief Vasyl Malyuk, targeted the bridge’s supports and caused structural damage without civilian casualties.

The bridge was briefly closed, reopened, and then shut again later in the day amid unconfirmed reports of further blasts. Russia has not officially responded, though military bloggers suggested an underwater drone may have been used. The SBU called the bridge a legitimate military target, BBC reported.
