Secret police agents abducted and beat award-winning blogger Yoani Sanchez, whose online reports chronicle the dark side of everyday life in communist Cuba, on her way to a march for non-violence, she said Saturday.

Three agents in street clothes snatched her and friend Orlando Luis Pardo off the street in the Havana district of Vedado.

"They beat me and then they shoved me into a car head first. They did not give me any explanation at any time, but it is clear their goal was to stop us from taking part in the march," Sanchez, who writes the blog "Generation Y," told AFP.

Two other friends of hers were ordered into police cars and released later, she added.
