A group of 33 Mexican soldiers is back home after crossing the Donna-Rio Bravo International Bridge in four military Hummers.
The soldiers surprised American officials at the bridge around 1:50 p.m. Tuesday.
U.S. Customs and Border Protection (CBP) spokes man Felix Garza said nobody was injured and the incident ended peacefully.
The soldiers spent a little more than three hours on American side of the bridge before being "processed" and being allowed to return home.
American officials would not confirm if the soldiers were fully armed but Garza said nobody was injured during the incident.
"I can't answer whether or not they were armed or not but I can tell you that they were conducting their work that they do as military and somehow they lost sight of the boundary line and entered U.S. territory," Garza said.
Border Patrol agents and local law enforcement agencies responded to the scene to support customs officers.
Garza said that customs officers quickly initiated the proper protocols for the situation.
"We continue to work with our partners in Mexico," Garza said. "We continue to have a shared responsibility over the security of the border and we maintain constant communication with them."
U.S. Immigration & Customs Enforcement officials told Action 4 News that they will continue to investigate the incident.
Mexico's Ministry of National Defense (SEDENA) reports that the soldiers "involuntarily" crossed the border.
SEDENA officials reported that soldiers had to continue on their path because the only vehicle turnaround was on the American side of the border.
