In Dilley, Texas, dozens of detained immigrant families held a protest Saturday inside ICE’s South Texas Family Residential Center demanding the release of detained children. Protesters held signs reading “Libertad para los niños,” or “Liberty for the kids.”

Detainees in Dilley include 5-year-old Liam Ramos, who was detained with his father in Minnesota after the boy came from preschool last week. Images of Liam went viral after he was picked up while still wearing his Spider-Man backpack and a blue hat with bunny ears.

Also being held at Dilley is a 7-year-old named Diana Crespo. She and her parents were detained in the parking lot of a hospital in Portland, Oregon, two weeks ago. Her parents were trying to get help for the second grader who had a long-lasting nosebleed — but they never made it inside the hospital. The Oregon Nurses Association condemned what happened, saying, “No parent should ever be forced to weigh their child’s health against the risk of detention.”
