Wagner Group revolt in Russia

On Saturday, the Wagner Group took control of a major Russian city, in one of the biggest crises of President Vladimir Putin's political career. Putin's long-time henchman, Yevgeny Prigozhin, authorized the revolt but soon backed down. Observers say the incident left an opening for Ukraine to exploit, but Russian airstrikes have continued unabated. And, Prigozhin's rebellion has raised many questions. We hear from Russia scholar Mark Galeotti about how vulnerable Putin remains and his response to the short-lived mutiny. Also, a new initiative is launching this August to end hunger among school children in Nairobi, Kenya. Plus, Elton John's first — and maybe only — appearance at Glastonbury.
