The speaker of Russia's lower house of parliament said Thursday that lawmakers might consider tougher legislation to prevent extremism after an attack on worshippers at a Moscow synagogue that wounded eight men, including three foreigners. The attack at the Chabad Bronnaya synagogue came amid an increase in the activity of hate groups in Russia and in the number of racist crimes. Jewish leaders said the attack should serve as a clear message to Russian authorities and the public to fight racism. Russian political parties, religious communities and the Foreign Ministry all condemned the attack. Parliamentary Speaker Boris Gryzlov said that while Russia had an adequate legal means to fight any form of extremism, "if it does not guarantee the absence of such incidents (as the attack) that means we should consider whether it is necessary to toughen this legislation."
