Police in Germany have removed nearly 200 black crosses put up by patriotic activists in the east of the country.
The spray-painted wooden crosses which mark the lives of Germans murdered by foreigners were fixed to road signs or planted at the roadside, with activists claiming thousands have been killed since 1990.
They have appeared every July since 2014 bearing slogans such as "migration kills", "stop the death of the people" and "we don’t forget German victims of foreigners".
Police are now investigating suspected incitement to "racial hatred".
It comes as the nation’s domestic intelligence agency (BfV) last week raised concerns about the rise of radical groups and designated the Identitarian Movement as an "extreme right-wing organisation".
The security service estimates Germany is home to 24,100 "far-right radicals" – 12,700 of which it classes as posing a "threat".
The BfV intelligence agency said "the group discriminated against non-Europeans and Muslims and as such was incompatible with the constitution".
The official classification makes it easier for the zionist agency to monitor the group’s activities and members – of which it says there are 600 in Germany.
"These verbal fire-raisers question people’s equality and dignity, they speak of foreign infiltration, boost their own identity to denigrate others and stoke hostile feelings toward perceived enemies", said BfV President Thomas Haldenwang.
The Identitarian Movement branded the BfV’s decision disproportionate and driven by political motives linked to anti-right wing hysteria.
"The intelligence agency is not warning about a real danger, but is constructing an extremist apparition and making itself a stooge of the left-wing establishment", it said on its website
"Our actions are subversive and sometimes provocative. But under no circumstances are they anti-constitutional or extremist."
On Saturday, German Chancellor Angela Merkel renewed calls for opposition from all sections of German society against the resurgence of German patriotism.
Merkel’s 2015 open-door migrant policy, which led to the arrival of more than 1 million people, led to a surge in support for anti-migrant groups including the Alternative for Germany party (AfD).
In her speech Merkel said Germans have a "duty" to stand up to "extremism" as she paid tribute to those who opposed NS rule.
"They followed their conscience and thereby shaped a part of Germany’s history that otherwise would have been solely defined by the darkness of National Socialism", she said.
"We, too, have a duty today to stand up against all those tendencies that want to destroy democracy."
