CHEMNITZ, Germany (AP) — Germany's far right is trying to make protests this weekend a watershed moment in which different nationalist groups — from lawmakers in national parliament to Hitler-saluting skinheads — will come together in a national anti-migrant movement to challenge the political establishment.

Several rallies by different far-right groups will merge on Saturday night, and organizers have invited concerned citizens to join the marches protesting the killing of a German man last week, allegedly by migrants from Syria and Iraq. They are hoping that unity could signal the beginning of a broad far-right pact in eastern Germany.

A rival rally by their opponents will test authorities' ability to keep the peace after scenes of vigilantes chasing foreigners in the city streets shocked Germany this week.
