President Vladimir Putin has long profited from the actions of the Wagner mercenary group, but the mutiny led by its chief Yevgeny Prigozhin presents the Russian strongman with a challenge that could irreparably damage his authority, analysts say.

Prigozhin declared he would take down the Kremlin’s defense leadership. Putin vowed to crush the rebellion. Here’s how events unfolded.

Prigozhin was killed when his plane crashed north of Moscow on Aug. 23, Russian authorities have confirmed.

The 19-year-old teenager tried to open the exit door mid-air but was controlled by cabin crew who used a lasso rope to capture the passenger.

Here is what global leaders are saying about the extraordinary situation taking place in nuclear-armed Russia.
