The Russian parliament has increased punishment for armed rebellion in response to the coup attempt mounted by mercenary leader Yevgeny Prigozhin last year to 15 from 12 years in prison, state media reported on Tuesday.
In serious cases where deaths result, for example, the penalty has been raised to life from 20 years, the TASS news agency reported.
Prigozhin marched with his Wagner Group on Moscow from southern Russia in June 2023, saying he was dissatisfied with the way the Russian general staff was conducting the campaign in Ukraine.
After making considerable progress towards the Russian capital, he called the rebellion off. He and some of his associates died three months later in a suspicious plane crash.
In its session, the Duma also increased punishments for foreigners in Russia who support attacks on the security of the Russian Federation either financially or organizationally.
The law could apply to migrants from Central Asia who assisted Tajik jihadis in their attack on a music venue in Moscow in March that killed more than 130 people.
