The migrant support group No More Deaths says U.S. Border Patrol agents routinely vandalize or confiscate humanitarian aid left by activists near the U.S. border with Mexico, condemning border crossers to die of exposure or dehydration in the harsh Sonoran Desert. In a report released Wednesday, the group found that between 2012 and 2016, Border Patrol agents emptied nearly 4,000 gallons of water left for migrants in the desert, while confiscating food, emergency medical blankets and other aid. No More Deaths also says Border Patrol agents frequently target the group’s volunteer activists for harassment.
