Russian President Vladimir Putin on Monday demanded concrete proposals on ensuring the security of the bridge linking southern Russia to Crimea after an attack overnight that he called a "terrorist act" that had caused serious damage.
Putin was speaking in a televised meeting with officials to assess the consequences of the attack.
Putin said later that his defense ministry was preparing proposals for a response to the overnight attack that damaged the road bridge linking Crimea to southern Russia, for which he blamed Ukraine.
At the end of a televised meeting with national and regional officials to assess the consequences of the attack, Putin called it a cruel and senseless act, as he said the bridge had not been used for months to supply Russian forces fighting in Ukraine.
Ukraine did not officially claim responsibility, but Ukrainian media said Ukrainian security services had deployed maritime drones.
