Mexican authorities probing grenade attack on US consulate

The state is the home base of the Jalisco New Generation Cartel, which is considered one of the most powerful gangs in Mexico by U.S. and Mexican authorities.

Mexican authorities are investigating an apparent grenade attack on the U.S. consulate in the city of Guadalajara, officials said on Saturday, underscoring the security challenges facing Mexico's new president.

The attack took place early on Saturday morning, local media reported, ahead of the swearing-in of President Andres Manuel Lopez Obrador later in the day.

No one was killed or injured in the attack and Mexican authorities are investigating the matter, according to a U.S. official in Mexico.

Jalisco state prosecutors wrote on their Twitter account that federal authorities had taken over the investigation of the incident.

The state is the home base of the Jalisco New Generation Cartel, which is considered one of the most powerful gangs in Mexico by U.S. and Mexican authorities.

The gang's leader, Nemesio Oseguera Cervantes, or "El Mencho" is on the U.S. Drug Enforcement Administration's most wanted list.

Violence has surged in Jalisco and across Mexico, which is seeing record levels of killings. Jalisco's incoming governor, Enrique Alfaro, is set to take power next weekend.
