The Council of Europe's secretary-general, Terry Davis, say the homophobic violence in recent weeks has been "neither isolated nor spontaneous."
Meanwhile, Russian gay activists say they are determined to hold a march in Moscow on May 27 to defend the rights of sexual minorities in Russia "whatever the response from the authorities."
Moscow Mayor Yury Luzhkov has justified his opposition to the march by saying most people oppose "these public expressions of sexual tendencies."
