In Mexico, police arrested two prominent immigration rights activists Wednesday. Cristóbal Sánchez was arrested by six plainclothes police officers outside his home in Mexico City and driven away in an unmarked car. And in the border town of Sonoyta, Sonora, police detained Irineo Mujica, director of the organization Pueblos Sin Fronteras, or People Without Borders. In a statement, the group called both arrests illegal and said the activists were targeted by the Mexican government for their humanitarian aid work with asylum seekers. Mujica has worked closely with Scott Warren, a humanitarian aid volunteer with the group No More Deaths in Tucson, Arizona, who faces up to 20 years in prison for providing water, clean clothes and beds to two asylum seekers in the Sonoran Desert. On Wednesday, Scott Warren told a jury at his trial his actions were motivated by three intentions: relief of suffering, respect for human dignity, and the right to self-determination.
