The human rights commission of the Organization of American States is warning about what it calls an "alarming" and "tragic" situation in Mexico involving not just drug violence but excessive use of force, impunity, torture and police collusion with criminals.

A report by the Inter-American Human Rights Commission cites increasing detentions of Central American migrants and attacks on journalists and human rights workers, many occurring under the administration of President Enrique Pena Nieto, who took office in 2012.

The report released Wednesday praises some recent judicial reforms, but says they haven't really been implemented yet. It says there have been no substantial changes in security policies and violence levels, highlighting reports of disappearances, extrajudicial executions and torture.
