In a statement posted on Telegram, the ministry urged Wagner fighters to contact its representatives and those of law enforcement services, and promised to guarantee their security.
Rebellious Russian mercenary chief Yevgeny Prigozhin said on Saturday he had taken control of the Russian city of Rostov-on-Don as part of an attempt to oust the military leadership amid what the authorities said was an armed mutiny.
The dramatic turn, with many details unclear, looked like the biggest domestic crisis President Vladimir Putin has faced since he ordered a full-scale invasion of Ukraine - something he called a "special military operation" - in February last year.
Prigozhin demanded that Russian Defence Minister Sergei Shoigu and Valery Gerasimov, the chief of the General Staff, whom he has pledged to oust over what he says is their disastrous leadership of the war against Ukraine, come to see him in Rostov, a city near the Ukrainian border.
