This month’s summits between America, Russia and Europe haves produced no concrete agreements on ending Ukraine’s war. On land, Ukrainian forces are limiting Russian advances on the eastern front to a slow, bloody crawl. At sea too, it is up to Ukraine’s drones, missiles and small boats to keep the Russians out.

Russia launched 72 drones and one ballistic missile into Ukraine overnight into Sunday, the air force in Kyiv said.

Kyiv has said its strikes are in response to Russia's attacks on Ukraine and are aimed at destroying infrastructure deemed crucial to Moscow's military efforts.
