European officials are cautiously watching the fallout from the apparent death of Yevgeny Prigozhin, whose short-lived attempt to overthrow the Russian defense leadership in late June put him in the crosshairs of Russian President Vladimir Putin.

Prigozhin’s reported death Wednesday — in a plane crash on a sunny, cloudless day traveling from Moscow to St. Petersburg — was not particularly surprising, coming on the two-month anniversary of his mutiny attempt.

However, it has still raised a flurry of questions, such as how Prigozhin’s death changes the security situation in Europe and if there’s any opportunity for Ukraine or Putin’s other foes within and outside Russia to exploit the situation.
