BERLIN (AP) — German police say they have seized several firearms from a couple believed to belong to the so-called Reich Citizens' Movement, a loose grouping of anti-government extremists, after authorities revoked their weapons permits.

Police in Flensburg, near the Danish border, said they sent in a tactical response unit to back up officers who were sent to the couple's home early Tuesday morning. The 73-year-old man and 69-year-old woman had been ordered to give up their two pistols, two revolvers and two rifles, and police say they handed them over when asked to do so.

In a similar operation in Bavaria last month, another self-styled Reich citizen opened fire on police raiding his property, fatally wounding an officer.

The Reich Citizens' Movement refuses to recognize the post-war Federal Republic of Germany.
