Mexico City faces traffic jams and security raids on July 31, 2026
On Friday, July 31, 2026, Mexico City experienced significant traffic disruptions as protests, marches and motorcycle rides blocked streets in the boroughs of Coyoacán, Cuauhtémoc, Iztapalapa and Gustavo A. Madero. The city’s command center reported road closures on the Viaducto Río de la Piedad and diversions to major avenues, while the weather service forecast temperatures of 26‑28 °C, heavy rain and winds of 40‑45 km/h. A magnitude‑5.0 earthquake near Mapastepec, Chiapas was recorded but did not trigger a seismic alert for the capital.
The federal security cabinet announced coordinated operations on July 30‑31 that resulted in dozens of arrests across Baja California, Jalisco, Tabasco, Tamaulipas, Oaxaca and other states. Authorities seized firearms, ammunition, tactical gear, large quantities of methamphetamine, marijuana, cocaine, vehicles and fuel trucks. In Oaxaca de Juárez, four suspects and two vehicles were detained. In Mexico City’s Milpa Alta district, 33‑year‑old Iván Lazcano Álvarez was arrested on suspicion of involvement in the May 2026 homicide of two U.S. citizens, with police confiscating marijuana, crystal cocaine, cash, a cellphone, a delivery‑type backpack and a scooter. The operations involved the Secretaría de Seguridad Ciudadana, the Guardia Nacional, the Mexican Army, the Navy, state police and federal prosecutors.
