Ukraine's air force said it destroyed 13 out of 26 missiles launched by Russia in a Thursday morning attack, including one Iskander ballistic missile and 10 cruise missiles.

Addressing the Wednesday report from the Ukrainian military that it sunk a Russian landing ship in the Black Sea, Zelenskyy said that Kyiv's forces had increased security on the waterway, which is one of Ukraine's key trade routes.

"This is important. Step by step we will clear the Black Sea of Russian terrorist objects," Zelenskyy said.
