Germany has returned over 4,600 individuals to Poland this year, with a significant number being Ukrainian, based on EU regulations and a Polish-German agreement. The Polish government is concerned about the return of migrants from Germany, urging explanations for incidents like German police leaving migrants on the Polish border. On the other hand, Russia has mobilized around 10,000 new citizens to join military operations in Ukraine, with an additional 30,000 individuals identified for shirking military registration requirements. These actions highlight Russia's efforts to bolster its military ranks using various means, including migrants and new citizens, amidst ongoing conflict with Ukraine.
