Mexican authorities have seized vials of counterfeit Keytruda, an expensive anti-cancer immunotherapy drug, during a raid following an ICIJ investigation into falsified pharmaceutical markets. The discovery confirms that fraudulent versions of the drug are circulating in distribution networks.

Mexican authorities discovered and dismantled a forced labor camp in Chihuahua's Sierra Tarahumara, where 21 men were being held in caves to cultivate poppies and marijuana for cartels. One victim had been captive for nearly three years; only four had been reported missing, indicating a hidden network of cartel-run slave labor camps with minimal public documentation.
