There was anger on the streets of Buenos Aires Sunday, after Argentina lost to Germany in the World Cup final.
Thousands of football fans had gathered in the city to celebrate their team's performance in the championship match. But hope turned to bitter disappointment after their 1-0 defeat.
Skirmishes broke out between riot police and youths.
Police fired tear gas at the youth, who threw rocks and tried to kick down shop fronts.
According to local media, 15 police officers were wounded in the clashes, which continued for more than three hours after the final result.
So far more than 50 people have been detained.
