Military expert warns Wagner boss Prigozhin to avoid upper floor windows.

A US military expert, William F. Wechsler, has warned that Yevgeny Prigozhin, the boss of Wagner Group, may be at risk of assassination after his aborted rebellion on Saturday. Wechsler said that Prigozhin should remember "When you strike at a king, you must kill him." Two Russian tycoons linked to critical comments on the war have fallen out of windows in the last year. Prigozhin led his mercenary group in an uprising on Saturday, only to call it off after coming close to Moscow.
