Kasparov Arrested at Kremlin Rally

Russian opposition leader Garry Kasparov was among about 170 people arrested as police moved against a banned anti-Kremlin rally in Moscow.

The former chess champion, charged with public order offences and then freed, declared Russia "was a police state".

The huge security operation was launched to prevent protesters from gathering at Pushkin Square.

President Vladimir Putin denies he is trampling on democracy, accusing the opposition of destabilising Russia.

Mr Kasparov leads the United Civil Front group, part of the opposition coalition The Other Russia.

He said he had been "walking with a group of people along the pavement without any slogans" when riot police had surrounded them.

"They grabbed everyone without distinction, without asking any questions," he said.
