Hundreds of migrant children and teens traveling without their parents have been held in jail-like detention centers at the border for 10 days, and longer, a DHS document obtained by NPR shows.
Under law, minors are only allowed to spend 72 hours in the detention centers, which are run by Customs and Border Protection.
But as of Thursday, more than 500 of the young migrants have spent more than 240 hours in the border facilities, according to the DHS documents.
Spokespersons for CBP and DHS did not immediately respond to a request for comment late on Thursday.
