Mexican officials say a leader of the Knights Templar drug cartel has been killed.

The officials said Enrique Plancarte died Monday in a clash with marines in the central state of Queretaro, but they wouldn't give other details. The officials spoke on condition of anonymity because they were not authorized to speak publicly about the case.

Plancarte was considered one of four leaders of the Knights Templar cartel, which is based in Michoacan state. The gang has been chased out of many Michoacan towns by vigilante groups that have demanded authorities go after the gang's leaders.

In recent weeks, Mexican security forces have killed the gang's top capo, Nazario Moreno, and arrested Plancarte's uncle and Templars leader Dionisio Plancarte.

Another leader Servando Gomez, known as "La Tuta," remains at large.
