BERLIN (AP) — A top lawmaker in the anti-migration Alternative for Germany party says its leaders will meet to discuss ways of avoiding a potential move by the domestic intelligence agency to put it under observation.

Alternative for Germany, or AfD, entered parliament last year and is now the biggest opposition party. Political opponents have increasingly called for the BfV agency to keep tabs on it amid fallout from the killing in the eastern city of Chemnitz of a German man, in which migrants are suspects.

They argue that recent protests point to an increasing blurring of boundaries between AfD and the extreme right neo-Nazi scene.

Parliamentary leader Alice Weidel said the party leadership will meet Wednesday to discuss the prospect of possible observation and "legal and organizational counter-strategies."
