Argentine protesters demand answers about missing activist
Tens of thousands of Argentines demonstrated in cities across the country holding photos of an activist who has been missing for a month.
Santiago Maldonado, 28, was last seen when border police evicted a group of indigenous Mapuche from lands in Patagonia owned by Italian clothing company Benetton.
Demonstrators in the Argentine capital marched to the Plaza de Mayo square in front of the presidential palace to demand the government find 28-year-old Mr Maldonado alive.
Since he disappeared on August 1, sympathisers from football great Diego Maradona to Oscar-winning composer Gustavo Santaolalla and politicians from opposing political parties have joined human rights activists in a social media campaign under the slogan: "Where is Santiago Maldonado?"
The disappearance has hit a raw nerve in Argentina, where human rights groups estimate that about 30,000 people died or were forcibly disappeared during the 1976-1983 military dictatorship.
"We've gone back in time 40 years. I can't accept it," said Rosa de Roisinblit, 98, the vice president of the Grandmothers of Plaza de Mayo human rights groups.
During the dictatorship years, she marched every week in the same square in Buenos Aires, fighting alongside other women in the group to recover their children and grandchildren.
"I can't believe that this is happening in a constitutional, democratically-elected government," she said.
Friday's march in the capital Buenos Aires was largely peaceful but at the end clashes erupted between groups that had apparently infiltrated the march, and police.
Mr Maldonado's case has become problematic for the government of President Mauricio Macri as human rights groups accuse it of being part of a cover-up and the Inter-American Commission on Human Rights has urged Argentina to find the missing artisan and tattoo artist.
Mr Maldonado's family says border police detained him when he and others were blocking a road in Chubut province, in the southern region of Patagonia. The authorities deny wrongdoing.
The case is being investigated as a forced disappearance.
But in a report published by local media written by local prosecutor Silvina Avila to the Inter-American Commission on Human Rights, she said there is no proof yet that border police were involved in the disappearance.
Mr Maldonado had joined the Mapuche cause while living in southern Argentina.
The August 1 protesters were demanding the release of Facundo Jones Huala, an imprisoned Mapuche leader who is wanted by Chile.
The lands belong to Compania de Tierras Sud Argentino, a wool-producing company owned by Benetton. Mapuches claim the lands as their ancestral territory and have been occupying them since 2015.
Some members of the Mapuche indigenous community have told reporters that Mr Maldonado was taken by border police.
"We want a serious and impartial investigation," his brother, Sergio Maldonado, told demonstrators on Friday.
"How much more must we ask ourselves: Where is Santiago?"
