Two people employed at the US embassy in Mexico have been wounded after their car was mistakenly fired on by police south of Mexico City, officials say.
The Mexican Navy said the US personnel were on a main road to the city of Cuernavaca when the shooting happened.
Details are still unclear, but the navy said the US vehicle had been fleeing from gunmen in another car.
The US state department said it was working with Mexican authorities to investigate the incident.
The BBC's Zoe Conway says the situation remains very confused.
