Images of a detention center for immigrant children show the conditions in which nearly 1,500 boys are sheltered in Brownsville, Texas.

Murals of presidential quotes could be seen inside, some of which feature quotes in both English and Spanish — including one of President Donald Trump saying, "Sometimes losing a battle you find a new way to win the war."

Children are allowed to leave the complex for only two hours each day. Many apparently have spent time inside watching the Disney animated film "Moana" and learning about US history.

A small group of reporters from outlets including MSNBC and The Washington Post were allowed to tour the facility on Wednesday. MSNBC correspondent Jacob Soboroff reported his observations and some pictures of the facility in a lengthy Twitter thread that evening.

The Administration for Children and Families at the US Department of Health and Human Services shared the photos with Business Insider on Thursday.

Casa Padre, which used to be a Walmart, is operated by Southwest Key, a firm that runs more than a dozen shelters in Texas housing unaccompanied immigrant children, the San Antonio Express-News reports.

The organization is contracted by the Office of Refugee Resettlement, a division of HHS that manages minors suspected of crossing the US border illegally and oversees their transfer to family custody or foster care.

While some children cross the border illegally without family members, the Trump administration has also implemented what it calls a "zero-tolerance" policy with regard to illegal border crossings by immigrant families. The policy calls for adults to be criminally prosecuted, causing them to lose custody of the children accompanying them.

The policy has been deeply controversial and emotionally fraught.

Miguel Nogueras, an assistant federal public defender, told CNN that roughly 500 children had been separated from their parents since May.
