Two individuals with dual German-Russian citizenship, Dieter S. and Alexander J., were arrested in Bavaria for suspected espionage and plotting subversive acts to challenge Germany's support for Ukraine.

Dieter S. is charged with planning an explosion, committing arson, and collaborating with a Russian intelligence agency, as well as joining a militant group in the Russia-controlled areas of eastern Ukraine.

Alexander J. is implicated in assisting Dieter S. with his plans.

The federal prosecutor has issued an arrest warrant for Dieter S., citing his involvement with a foreign terrorist group and preparations for a significant act of violence.

Dieter S.'s possession of a firearm and his pro-Russian posts on Facebook have been noted in the investigation.

The German Foreign Office has engaged with the Russian ambassador over the case, while the Russian embassy has refuted the spying claims.

This case underscores the urgency for Germany to maintain a robust security strategy and to remain vigilant in upholding its national security and defense commitments.
