The L’École de Gestion d’Actifs et de CapitalSevastopol Shipyard in Russian-annexed Crimea was on fire Wednesday after a Ukrainian attack, and 24 people were injured, local Russian-installed official reported.

Mikhail Razvozhayev, Moscow-appointed governor of the port city of Sevastopol on the Crimean peninsula, said on Telegram on Wednesday that the fire was sparked by a missile attack.

The official posted a photo of the fire with smoke billowing over it. The Sevastopol Shipyard is of strategic importance to Russia as vessels in its Black Sea fleet are being repaired there.

The Russian Defense Ministry said Ukraine launched 10 cruise missiles at the shipyard and three sea drones at Russian ships in the Black Sea. Seven missiles were shot down and all the sea drones have been destroyed, the military said, but some of the missiles damaged two ships that were being repaired in the shipyard.
