Fourteen police officers have been killed and three injured in a shooting in western Mexico.
The police were carrying out a court order in el Aguaje, Michoacán state, when their convoy was ambushed.
A powerful criminal group, the Jalisco Nueva Generación cartel, is believed to have carried out the attack.
Authorities said all resources would be put into finding those responsible. The region is a hotspot for violence linked to turf wars between drug cartels.
Mexican president Andrés Manuel López Obrador has been trying to tackle drug crime since he took office last December
