Mexican security services announced the seizure of over 1,100 kilograms of fentanyl, marking the largest bust in the country’s history. The operation, facilitated by intelligence from informants, took place in Sinaloa and carried a significant impact on drug traffickers, estimated at $400 million. The announcement coincides with heightened violence between Sinaloa cartel factions following the arrest of notorious drug lord Ismael ‘El Mayo’ Zambada. U.S. President Donald Trump has pledged to pressure Mexico into taking stronger actions against fentanyl exports.
