Mexico has announced legal and diplomatic action following the deaths of seventeen of its citizens, either in US immigration enforcement operations or while in detention, since President Donald Trump returned to office. The Mexican government is filing complaints with US state prosecutors and has sent formal cease-and-desist letters to detention centres where Mexican nationals have died, raising concerns about medical care and detention conditions. It also plans to submit a complaint to the US justice department and has asked the UN human rights commissioner to find out if the deaths comply with international human rights obligations. The measures follow the fatal shooting of a Mexican citizen in Houston on 7 July during an ICE immigration raid. Claudia Sheinbaum has said that although Mexico does not seek confrontation with the USA, it could not remain silent. ‘We must raise our voices when there are human rights violations against our fellow citizens’, she said.
