American law enforcement officials have arrested two top leaders of the Sinaloa Cartel, a major criminal organization in Mexico. Ismael Zambada GarcÃa and JoaquÃn Guzmán López, powerful drug traffickers, were apprehended in El Paso, Texas. The arrests were a culmination of years of pursuit by the F.B.I., DEA, and Homeland Security Investigations. Attorney General Merrick Garland emphasized the threat of fentanyl and vowed to hold all responsible cartel members accountable. The capture of these leaders is expected to impact the cartel's operations and could lead to increased violence as factions vie for control.
