JAKARTA - The Indonesian Embassy in Mexico City issued a public advisory urging Indonesian nationals to stay home and avoid non-essential activities outside following a wave of cartel violence that swept the country on February 22.

The unrest was set off by the Mexican military's killing of Nemesio Rubén Oseguera Cervantes, known as El Mencho, the leader of the Jalisco New Generation Cartel. The Mexican Secretariat of National Defence said he was killed in a major military operation in the town of Tapalpa, in Jalisco state.

The U.S. State Department had offered a $15 million reward for information leading to his capture.

Authorities said more than 70 people died during the attempt to capture Oseguera Cervantes and in its aftermath, a toll that included security forces, suspected cartel members and others. The cartel responded with widespread violence, and authorities announced late Sunday that they had cleared most of the more than 250 roadblocks set up across 20 states.

The embassy told Indonesians to stay calm, follow instructions from local authorities, avoid riot-affected areas, refrain from going outside unless it was urgent, and monitor the situation closely. It also directed nationals to call 911 or the embassy's emergency hotline at +52 55 6298 5506 if needed.

The violence puts pressure on Mexico ahead of a high-profile summer. Guadalajara's Estadio Akron, home to Liga MX's top team C.D. Guadalajara and the Mexico national football team, is set to host four group-stage World Cup matches, including Mexico against South Korea on June 18.

FIFA's president, Gianni Infantino, expected a total of over seven million people attending the 104 matches of the World Cup, which is also hosted by the United States and Canada.
