Nemesio Rubén Oseguera Cervantes, who went by the nickname "El Mencho," led one of Mexico's most powerful crime syndicates and had been one of the world's most wanted cartel leaders for several years.
During the military operation in which he was killed, roadblocks with burning vehicles were set up in Jalisco and other states - a tactic that cartels use to disrupt military operations against them.
The US had announced a reward of up to 15 million, equivalent to around 136 million kronor, for information leading to the arrest of "El Mencho."
In February, the United States classified the cartel as a foreign terrorist organization.
