WASHINGTON The United States warned its citizens to avoid certain parts of the Frankfurt subway on Saturday because of anticipated violence around Neo-Nazi demonstrations and counterdemonstrations.

A "strongly anti-foreigner" Neo-Nazi group called "citizens for our country" planned to travel from Frankfurt's main train station via the subway, or U-Bahn, to Danziger Platz to assemble near the zoo, the state department said in a statement originally released by the U.S. consulate in Frankfurt.

They were to be joined by other right-wing groups, while left-wing groups vowed to hold counterdemonstrations.

"In the past, many of these demonstrations have resulted in violence," the statement said.
