U.S. Border Patrol on Tuesday morning apprehended its largest group of illegal immigrants caught at once, Customs and Border Protection (CBP) reported.

CBP said 424 illegal immigrants were apprehended just after midnight in Sunland Park, New Mexico; an additional 230 illegal immigrants were apprehended in Antelope Wells, N.M., around 2 a.m.

“This is an ongoing situation that U.S Border Patrol agents are facing in southern New Mexico: hundreds of parents and children being encountered by agents after having faced a dangerous journey in the hands of unscrupulous smugglers,” CBP said in a statement. “Criminal organizations continue to exploit innocent human lives in order to enhance their illicit activities without due regard to the risks of human life. In most cases these smugglers never cross the border themselves in order to avoid apprehension.”
