Protesters come out in support of jailed anti-Putin punk rockers

They're asking for undies on heads, masks, and as much color as possible. Organizers of protests in more than three dozen cities around the world are hoping for thousands to turn out in raucous support of the Russian femme provocateurs Pussy Riot, who are facing sentencing Friday in Moscow.

The three women in the band have been in jail for more than five months because of a prank in Moscow's main cathedral against Russia's Vladimir Putin, and face a maximum seven years in jail.

Celebrities including Paul McCartney, Madonna and Bjork have called for them to be freed, and protests are planned around the world Friday. The trial has attracted worldwide attention as an emblem of Russia's intolerance of dissent.
