The violence that followed the killing of a cartel leader in Mexico is fueling fears that the bloodshed could hurt tourism ahead of the FIFA World Cup later this year.

Sunday's killing of Nemesio Rubén Oseguera Cervantes, "El Mencho," triggered roadblocks and unrest across western Mexico.

The death of Nemesio “El Mencho” Oseguera is likely to spark a nationwide battle for control of the Jalisco cartel.

U.S. citizens and government staff in affected parts of Mexico are being asked to stay at home, work remotely and avoid crowds.

"El Mencho," the powerful drug lord the Mexican army killed in a daring raid Sunday, had created what security experts say was one of the most advanced security operations devised to protect a cartel boss. His system relied on high-powered weaponry, nearly 400 gunmen, bomb-delivering drones and, sometimes, landmines.
