Ukrainian forces shot down scores of exploding drones and six cruise missiles from a pre-dawn Russian attack on the port of Odesa on Tuesday, Ukrainian authorities said, a day after Moscow broke off a deal that had allowed Kyiv to ship vital grain supplies from the Black Sea city during the war.

The Russians first sought to wear down Ukraine’s air defenses with the drones and then targeted Odesa with six Kalibr cruise missiles, the Ukrainian military’s Southern Command said. All six missiles and 25 drones were shot down by air defenses in the Odesa region and other areas but debris and shock waves caused some damage.
