Mexican prosecutors have charged 14 federal police officers with trying to kill two CIA officers and a Mexican navy captain in an August ambush south of the capital city.

In its Friday statement, the Attorney General's Office doesn't state a motive for the attack. The police officers have been charged with attempted homicide.

The statement says the police officers were off-duty and driving private vehicles when they opened fire 152 times on the U.S. Embassy vehicle carrying the CIA officers and navy captain. The targets were heading to a military training camp when they were injured in the attack.

The Mexican officers have spent nearly 80 days in a form of house arrest Mexico uses in organized crime cases.
