One soldier was cited in possession of marijuana for personal use, CBP said in a statement, and all were returned to Mexico within five hours.

Contacted Mexican military leaders and the soldiers and their equipment were returned to Mexico by 5 am, CBP said.
The Mexico Secretariat of National Defense did not immediately respond to a request for comment.
