Moscow, Aug 12 (AFP)- Russia's Foreign Ministry condemned on Saturday what it called Ukraine's "terrorist attack" on the Crimean Bridge, saying it put innocent civilians' lives at risk, and vowed retaliation.

"There can be no justification for such barbaric actions and they will not go unanswered," ministry spokeswoman Maria Zakharova said in a statement on the Telegram messaging app.

Earlier, Russia's Defence Ministry said its forces had thwarted a Ukrainian rocket attack on the 12-mile (19 km) bridge, which links Russian-annexed Crimea to Russia across the Kerch Strait.

The ministry said Russian forces had also shot down a number of Ukrainian drones targeting the peninsula.
