MEXICO CITY (AP) — Mexican marines killed an alleged gang leader and seven of his bodyguards, authorities in the central Mexico state of Puebla said Monday.

State prosecutor Gustavo Huerta said the gang leader, known as "Comandante 30," was responsible for the death of six municipal police officers executed in Puebla in June.

He also said the leader and his bodyguards were escorting a truck carrying stolen fuel on Sunday when they opened fire on a Marine patrol that spotted them. There were no casualties among troops.

State police chief Jesus Morales said Comandante 30 had been posting videos in recent weeks claiming to represent the Jalisco drug cartel.

A campaign of attacks on his rivals were "destabilizing the state of Puebla," Morales added.

Puebla has been a flashpoint for violence related to fuel thefts from government pipelines.
