Venezuela detains dozens in protest

Police in Venezuela have detained at least 80 demonstrators who were demanding the release of those arrested in recent anti-government protests. Hundreds of people, mostly students, had marched peacefully through the streets of the capital Caracas. But security forces later clashed with a group of demonstrators who threw stones and home-made explosives, and tried to erect barricades.
