23 anti-World Cup protesters jailed

A judge in Rio de Janeiro Friday ordered 23 people jailed for "violence" during anti-World Cup protests, including those arrested before the Argentina-Germany final.

Judge Flavio Itabaiana de Oliveira Nicolau said the decision was made because of "the danger the accused pose to the public."

Of the 23, two of those jailed are accused of the death of a Brazilian TV cameraman who was killed when he was struck by a flare.

Minutes before the final, police launched tear gas and stun grenades to disperse some 300 anti-Wold Cup protesters who tried to march toward Rio de Janeiro's Maracana Stadium.

But World Cup protests on the whole were much smaller that the the mass protests that rocked Brazil during last year's Confederations Cup.
