JALISCO, MEXICO — Mexico’s most wanted drug lord, Nemesio Oseguera Cervantes, known as “El Mencho”, has died at the age of 59 following a military operation in western Mexico, authorities said. The United States provided intelligence support for the operation. His death triggered violent unrest in multiple states, with armed groups blocking highways, torching vehicles and clashing with security forces in areas long associated with his criminal network. El Mencho was shot in Tapalpa, in the western state of Jalisco, considered a stronghold of his organisation. Officials said he died while being transported to hospital. Mexico’s security cabinet later said that road closures imposed during the unrest had begun to ease, though security operations remain ongoing in several regions. Widespread disruptions Violence following his death disrupted daily life across parts of western and central Mexico. Local media showed buses and commercial vehicles set ablaze, while some highways were temporarily closed due to security concerns. Air travel was also affected. Several airlines cancelled or diverted flights to and from Puerto Vallarta and Guadalajara, two major cities in Jalisco state. Puerto Vallarta is one of Mexico’s most popular beach destinations for North American tourists. Airlines including Air Canada and United Airlines temporarily halted services to Puerto Vallarta amid security concerns. Other carriers reported disruptions as authorities sought to stabilise affected areas. The United States Department of State issued a travel advisory urging Americans to exercise caution, while Canada updated its own guidance for travellers in parts of Jalisco. A powerful cartel figure El Mencho was widely regarded as one of the most powerful drug traffickers in Mexico. The United States had offered a reward of up to $15 million for information leading to his capture. A former police officer, he built a sprawling criminal organisation that trafficked cocaine, methamphetamine and fentanyl into the United States. U.S. authorities have accused his network of playing a major role in the flow of synthetic opioids, including fentanyl, which has contributed to tens of thousands of overdose deaths annually in North America. Earlier in his career, Oseguera Cervantes was arrested in California on drug-related charges and served time in prison before being released and returning to Mexico in his 30s. After older cartel leaders were killed or captured, he rose rapidly to prominence, consolidating power in Jalisco and expanding operations across other regions. Mexican authorities have accused him of orchestrating assassinations of rival traffickers and ordering attacks against security forces. His organisation became known for its heavy weaponry and ability to challenge state forces directly. Uncertain aftermath Security analysts say the death of a major cartel leader can lead to short-term spikes in violence as factions compete for control. It remains unclear who will assume leadership of his organisation or whether internal rivalries could intensify instability in affected states. Mexican officials have not yet provided detailed information about the broader operation that led to his death, though they described it as a targeted military action supported by U.S. intelligence. For now, authorities say the immediate wave of road blockades has subsided, but security patrols remain heightened in Jalisco and neighbouring states. The killing marks one of the most significant blows to organised crime in Mexico in recent years, but experts caution that dismantling a cartel’s leadership does not automatically dismantle its operational structure.
