The Russian Defense Ministry said that it launched a "massive strike using long-range precision air, land, and sea-based weapons and attack drones."

A Russian missile strike hit a grain-carrying cargo vessel off Odesa, killing five crew members. Ukrainian officials said the ship had an international crew and was transporting corn, calling the attack another strike on global food security.

Ukraine launched 400 drones on Russia's capital on Sunday night following a series of strikes over the weekend.
