Mexico City: Mexican authorities have accused seven police of torturing three women who survived an alleged slaughter by the military a year ago, prosecutors said.
Investigators have enough information to charge the seven with physically and psychologically abusing the women, they said late Wednesday in a statement.
Twenty-two people, one of whom was aged under 15, died in the June 30, 2014 clash in Tlatlaya in Mexico State.
The killings have been portrayed as one of the worst abuses by the military since 2006, when the army was sent into the streets by then president, Felipe Calderon, to fight drug cartels.
Witnesses told local media that people were killed execution-style after surrendering.
A national human rights body determined at least 12 people were extra-judicially killed by police.
International organizations including Amnesty International and the United Nations made appeals for justice to be done in the case on its anniversary.
Twenty officials in the state of Mexico are being probed for their handling of the case.
