In a strong blow to one of Mexico's most notorious drug cartels, Mexico's navy killed a top drug kingpin in a shootout Wednesday at an upscale resort.
Arturo Beltran Leyva, head of the Beltran Leyva cartel, was killed in the Mexican city of Cuernavaca, the navy said.
Six other cartel members died in the gunbattle at a housing complex called Altitudes, navy spokesman Adm. Jose Luis Vergara said Thursday. He added that one of the gang members killed himself as authorities closed in.
Three navy personnel were wounded by hand grenades, one fatally, President Felipe Calderon said from the U.N. climate conference in Copenhagen, Denmark.
Navy 3rd Petty Officer Melquisedet Angulo Cordova died while being treated 
for his injuries, he said. One of the other two navy men was in serious condition, and the other was in stable condition, Vergara said.
The Beltran Leyva cartel is one of the most violent and feared drug organizations in Mexico.
Authorities presented to the media three people -- two women and a man -- who were arrested in the raid. Their role with the cartel was not made clear.
The arrested women were identified as Catalina Castro Lopez and Gabriela Vega Perez. The man's name was not immediately released.
Arturo Beltran Leyva was one of Mexico's top three most-wanted criminals, Calderon said.
