Amnesty International says Mexican soldiers have carried out torture and forced disappearances while fighting drug cartels.
The group says one case involves 25 Tijuana police officers detained on corruption allegations. The officers say troops put their feet in water and applied electric shocks to their bodies, including their genitals.
The Interior Department says it will analyze the report released by the human rights watchdog group on Tuesday. It also details four other cases of abuse against 10 people in the northern border states of Chihuahua, Tamaulipas and Baja California, where Tijuana is located.
More than 45,000 troops have been deployed to drug hot spots since President Felipe Calderon took office in 2006.
