A high ranking leader in the Beltran-Leyva Cartel, Juan Francisco Patron Sanchez (also known as “H2”) and seven of his drug cartel members were shot and killed in the western state of Nayarit, Mexico by the Mexican Military.

A Mexican Navy official who was not authorized to be quoted by name said Friday that Patron and seven accomplices had opened fire on marines and had barricaded themselves in the upper part of a house in the Nayarit state capital of Tepic.

The official said that a helicopter gunship had been called in to provide “dissuasive fire,” to suppress outgoing gunfire from the structure on Thursday.

Use of such “minigun” weapons from a helicopter gunship is extremely rare in urban areas. They apparently have been used before by Mexican police, but usually only in rural areas.
