Ukraine hit the Sevastopol Shipyard in Crimea in a missile attack overnight, causing a fire and wounding at least 24 people, while Russia damaged Ukraine’s Izmail port on the Danube river.

The attack sparked a fire at a “non-civilian facility” in the South Bay area of the Sevastopol Shipyard early Wednesday, Russia-installed Governor Mikhail Razvozhaev said on his VK social network page. Four of the people injured are in moderate condition, he said. The fire service is working on the site.

Seven of 10 cruise missiles were shot down, Russia’s Defense Ministry said on its Telegram channel. Two ships that were under repair were damaged, it said.

Crimea, which Russia annexed from Ukraine in 2014, regularly comes under attack by drones or missiles. The Crimea bridge linking mainland Russia and the peninsula was partially damaged in July.

Ukraine’s Izmail port in the Odesa region was hit in a series of Russian drone strikes, Governor Oleh Kiper said on his Telegram channel. Rescue workers are putting out the fire.

Six people were injured, with three in serious condition, Kiper said.

The port, along with others on the Danube River, has become increasingly vital to Ukraine’s crop shipments since Russia’s withdrawal from a deal to allow grain exports via larger Black Sea ports.
