German authorities arrested a Yemeni national suspected of joining the Houthi movement and taking part in combat operations in Yemen, federal prosecutors announced on Thursday.

The man, identified as Hussein H. due to Germany’s strict privacy laws, was apprehended in the town of Dachau, near Munich. According to prosecutors, the suspect is believed to have become involved with the Houthis as a teenager.

Officials allege that Hussein H. joined the group in October 2022, undergoing “ideological indoctrination” followed by military training that lasted approximately three months. He is then said to have participated in combat briefly in the Marib region of Yemen in early 2023.
