Six people including a police officer were killed on Saturday in central and northern Mexico, bringing to nine the law enforcement death toll in the country in 48 hours, officials said.
A police officer was shot and killed and his partner gravely wounded in central Mexico state after they responded to a public altercation. State authorities said the pair were disarmed and executed by thugs, who were later apprehended by police.
The murder brought to nine the police officers killed in 48 hours, including a Federal Police commander and his bodyguard shot to death Thursday in a Mexico City restaurant, and six officers killed later that day in Culiacan, Sinaloa state.
Five other people -- two men and three women -- were shot dead Saturday in the northern border state of Chihuahua, local officials said. Two of the women were shot dead in Ciudad Juarez, on the US border.
More than 450 police officers have been killed since December 2006, when President Felipe Calderon deployed 36,000 military troops and thousands of police around the country in an operation aimed at clamping down on organized crime.
The highest death toll of the drug war is in Ciudad Juarez, where some 500 people have been killed this year.
