Authorities in Argentina have issued warnings regarding a viral social media trend known as the ‘48-hour challenge,’ which encourages adolescents to leave home and cut contact with families for two days. Organizations such as Grooming Argentina and the Córdoba Police noted that the trend increases risks of violence, manipulation, and judicial intervention.

Separately, search operations have been launched for missing individuals in river-related incidents. In Santa Fe, Argentina, a 19-year-old went missing in the Salado River after a canoe was carried away by currents; tactical divers and police units have been deployed to locate him. In Guasave, Mexico, a 19-year-old also disappeared in the Sinaloa River, prompting civil protection search efforts in areas with strong currents.
