6 police officers killed, 4 wounded in Mexico ambush after fighting "heroically" in outnumbered attack, officials say

Six police officers were killed and four others wounded Sunday in the northern Mexico border state of Nuevo Leon after they were ambushed by a presumed drug gang equipped with 10 homemade armored cars and heavy weaponry, authorities said.

Nuevo Leon state police said the patrol was outnumbered in the pre-dawn attack on a highway leading to the Colombia border crossing. The force said the officers performed "heroically" in the attack.

"The Civil Force reiterates their commitment to safeguard the residents of Nuevo Leon and committing that these acts do NOT go unpunished," the force said.
