Zaur Gurtsiev, a retired Russian commander who led airstrikes on the Ukrainian port city of Mariupol died in a blast Thursday in Russia, authorities said.

Ukraine’s drone attack against Russian airfields was audacious and daring. But most of all, it was meticulously planned and flawlessly executed. Kyiv struck where it could make a difference, damaging or destroying military aircraft that Moscow has been using to terrorize Ukrainian civilians with near daily aerial attacks.
