Russian President Vladimir Putin signed a law to mobilize citizens with criminal records of murder, robbery, drug trafficking, and other serious crimes under the Criminal Code of the Russian Federation for military service, CNN reported on Saturday. However, the criminals exempted from compulsory service are those who committed sex crimes against minors, were involved in the assassination of a government official, terrorism, or extremist activity.

Putin said Friday that the Kremlin had already mobilized an additional 18,000 soldiers in its war in Ukraine and earlier this week, the Russian Ministry of Defence suspended all of its partial mobilization activities. Putin’s partial mobilization order will only end when the Russian President signs in an official decree, reported CNN.
