MEXICO CITY, July 13 (Reuters) - Mexico has begun filing criminal complaints with state prosecutors in the United States over the deaths of its citizens in U.S. immigration custody and during enforcement operations, the foreign ministry said on Tuesday.
Mexico's government has also sent cease-and-desist letters to U.S. detention centers were Mexican nationals have died, the ministry added in a statement.
