The commander of Russia’s Black Sea Fleet appeared at a meeting in footage released by the country’s Defense Ministry on Tuesday, leading Ukraine to say it was “clarifying” whether he was dead or alive — a day after claiming to have killed him in a missile strike.

The video and photos appeared to show Viktor Sokolov, one of Moscow’s most senior naval officers, taking part in a video conference of military leaders that was led by Russian Defense Minister Sergei Shoigu.

NBC News has not verified when or where the footage was recorded.

[As I remarked on Twitter, the US has made erroneous claims from targeted strikes. We pronounced several AQ and ISIS leaders dead multiple times before actually killing them. It’s best to take these reports with a grain of salt until independent verification takes place. But that’s also true of proof-of-life claims like this from the Russians. — Ed]
