The rallies follow violent clashes Saturday between police and about 5,000 football fans and nationalists just outside the Kremlin walls in which 34 people were injured.

Dozens of nationalists staged a picket Sunday at the Federal Security Service headquarters to protest what they described as discrimination against ethnic Russians in favor of ethnic minorities.

On a central Moscow square, hundreds joined an opposition rally to demand Putin’s resignation. Opposition leaders said his policies have aggravated ethnic tensions.
