Russian Military Jet Crashes Into Sea Off Crimea, Says Governor

Sevastopol, the historic headquarters of Russia's Black Sea fleet, sits on the southern tip of Crimea, the Ukrainian peninsula annexed by Moscow in 2014.

A Russian military plane crashed Thursday into the sea off Ukraine's annexed Crimean peninsula, the Moscow-installed governor of the city of Sevastopol said.

"A military plane has fallen into the sea," Mikhail Razvozhayev said in a post on Telegram, without giving the cause.

Footage on social media showed a plane in flames falling out of the sky.
