The Mexican government has launched a comprehensive effort to address the deaths of 14 Mexican nationals in US immigration detention centers or during enforcement operations since 2025. Mexico is calling for thorough investigations, legal action, and diplomatic pressure to shed light on the 'persistent operational shortcomings' and 'negligence' it says have led to these fatalities.

Why it matters
