Argentine police have clashed with rioters in the capital Buenos Aires after the country’s defeat to Germany in the football World Cup final.
Thousands of people had earlier gathered around at the city’s Obelisk monument to party despite the result.
However, later in the evening, the scene turned violent as dozens of youths began throwing rocks at police and damaging store fronts.
At least 50 people were detained and 15 police officers were reported injured.
The mood among the crowd that had gathered after the match was initially good-natured, the BBC’s Wyre Davies reports from Buenos Aires.
However, late on Sunday evening rioting broke out on the Avenida 9 de Julio, the city’s main thoroughfare, our correspondent reports.
Police fired tear gas and rubber bullets at rioters. Some incidents of looting were also reported.
Local media reported that hardcore football fans were responsible for some of the violence.
Parents could be seen running away from the violence with their children.
Before the violence, many had gathered to celebrate Argentina’s performance in the tournament, with many saying they were still proud of the team.
“We have nothing to regret, we played first rate,” Horacio Laseira told AP.

Nothing quite matches the impact of sporting disappointment, of losing a big final.
Throughout the day, excitement had been building in Buenos Aires. It seemed that all of those Argentine fans who hadn’t made the journey north to Rio were descending on the Plaza San Martin in the heart of capital.
Two hours later, the park was a sea of mud, empty beer cans and dashed hopes.
Unlike the host nation, Brazil, who’ve had a disastrous tournament on the pitch, Argentina have exceeded expectations and came very close to winning their third World Cup title.
The team is expected to arrive back in Buenos Aires from Brazil later on Monday.
“I’m going to the airport to welcome them home and thank them for everything, they deserve it,” fan Lorena Hak told Reuters.
