From a Wall Street Journal story by Bojan Pancevski headlined “Wagner’s Prigozhin Planned to Capture Russian Military Leaders”:

Mercenary leader Yevgeny Prigozhin planned to capture Russia’s military leadership as part of last weekend’s mutiny, Western officials said, and he accelerated his plans after the country’s domestic intelligence agency became aware of the plot.

The plot’s premature launch was among the factors that could explain its ultimate failure after 36 hours, when Prigozhin called off an armed march on Moscow that had initially faced little resistance.
