Kasparov questioned by Russian state security agency

Investigators from Russia's security agency today questioned opposition leader Garry Kasparov, days after massive police crackdowns on anti-government protests in Moscow and St Petersburg last weekend.

Kasparov was summoned by the Federal Security Service, or FSB, the main successor of the Soviet KGB, to discuss recent statements that the agency believes may constitute illegal calls for extremist activity, his aide Marina Litvinovich said.
