Human Rights Watch on Sept. 2 called for the Chilean National Congress to reject a proposed package of constitutional amendments addressing "national security" questions being pushed by President José Antonio Kast. HRW charged that the amendments, supposedly aimed at fighting organized crime, would undermine due process and human rights protections.

Amnesty International on Aug. 19 accused Argentina of putting in place a "techno-authoritarian" surveillance infrastructure without adequate legal safeguards, as the government's newly created AI security unit expands state monitoring powers over citizens' online communications and physical movements.

UN human rights experts on May 29 called on Brazil to ensure full justice, accountability and reparations for victims and families affected by the 2006 "Crimes of May." They warned that continued impunity worsens the suffering of victims and perpetuates systemic racism and police violence. The experts said the killings and "enforced disappearances" should be recognized as serious crimes against human rights.

In a move sparking outrage from the country's nationalist and Peronist opposition, Argentina's central government under President Javier Milei has taken control of the port of Ushuaia—the country's southernmost seaport and a key gateway to Antarctica. Milei's move places operation and administration of the port under the National Ports & Navigation Agency (ANPyN), a body of the executive branch, for one year—over the objections of the Tierra del Fuego provincial government. Milei, in turn, says corruption by the local authorities mandated the move.

The rising wave of far-right populism has arrived in Chile with the run-off presidential election of Dec. 14. José Antonio Kast, a 59-year old ultra-conservative who campaigned on fighting crime and carrying out mass deportations, defeated left-wing candidate Jeanette Jara by about 16 points. His victory marks the country's furthest shift to the right since the restoration of democracy after the brutal dictatorship of Augusto Pinochet 30 years ago—an era and figure Kast has openly admired.

Paraguay authorities have arrested 26 suspects, dismantled two criminal networks, and identified 12 companies engaged in systematic illegal deforestation and trafficking of native tree species. The Paraguayan government, along with INTERPOL and 14 other agencies, launched Operation Panthera Onca to combat environmental crimes and the exploitation of natural resources in the Tri-Border Region where Paraguay, Brazil and Argentina meet.

The Argentine government of far-right President Javier Milei announced April 13 that it has placed its borders on alert due to potential infiltration of operatives linked to Iran and Hezbollah. There have long been concerns about a Hezbollah presence in the Triborder Region where Argentina, Brazil and Paraguay meet. But Interior Minister Patricia Bullrich in making the announcement this time emphasized a supposed threat from Bolivia.

The US District Court for the Southern District of New York unsealed an indictment Dec. 20 filed against Hezbollah operative Samuel Salman El Reda for his alleged involvement in a bomb attack on a Jewish community center in Argentina three decades ago. The 20-page indictment concerns the 1994 bombing of the Asociación Mutual Israelita Argentina (AMIA) in Buenos Aires, which killed 85 people and caused hundreds of injuries. The US government claims El Reda collaborated with the Hezbollah-linked Islamic Jihad Organization (IJO) in the attack.
