Camargo, Tamaulipas - Gunmen opened fire on the Mexican side of the Rio Grande City-Camargo International Bridge Saturday morning.
Tamaulipas officials confirmed the attack on the state's emergency notification system about noon amid a flurry of unconfirmed rumors about the assault, providing few details about the incident. A Mexican customs facility at the port of entry was damaged, but officials did not report any injuries during Monday’s confrontation between federal authorities and the armed civilians.
Also that morning, officials found three bullet-riddled bodies in the city’s Rancherias community.
Calls made to Camargo city officials were unanswered Saturday.
U.S. customs officials said they "are aware of what's going on in Mexico," but the incident has not affected operations at the American portion of the bridge.
"Whatever happened, happened in Mexico," said Eddie Perez, a spokesman for U.S. Customs and Border Protection. "Not here."
Perez said there was no southbound traffic at the port of entry, but he could not confirm whether bridge owners or Mexican officials had blocked off southbound lanes.
Voicemail messages left for Starr Camargo Bridge Co. were not returned Saturday.
Starr County Sheriff Rene Fuentes said officials at the port of entry requested units to monitor the American side of the bridge in case the attacks reach his jurisdiction.
"We’re hearing that 15 to 20 trucks of bad guys attacked the Mexican side," the sheriff said. "We’ve got a lot of people coming in to Rio Grande City from the Mexican side."
One woman who asked not to be identified said shots rang out at the H.E.B. grocery store in Rio Grande City. People rushed inside the building to seek shelter from the gunfire, she said.
Hidalgo County Sheriff Lupe Treviño said he has placed three SWAT units and 30 additional deputies on alert as a precaution.

Violence temporarily closes Camargo bridge
Authorities have temporarily shut down the Camargo-Rio Grande City International Bridge following reports of a robbery and shooting on the Mexican side.
Witness reports about a shooting on the Mexican side of the bridge on Saturday morning.
Witnesses said a group of armed men robbed a tollbooth or tollbooths on the Mexican side of the border and fired their weapons.

Southbound traffic from the United States into Mexico remained closed on Saturday afternoon.
Officials had not given a word on when it would be reopened but that two customs officers from Mexico remain unaccounted for following the attack.
The SSP reported that the bodies of three men were found near Camargo in the Town of Rancherias on Saturday morning.
Investigators reported that the three men had been killed by gunfire.
Authorities did not release the identities of the men and there was no immediate information to suggest the two incidents are related.
The two incidents are the latest in a string of shootouts and mysterious murders along the "frontera chica," or little border which extends from Camargo in the east to Nueva Ciudad Guerrero next to Falcon Lake.
Since late February, the area has seen dozens of deaths and disappearances following shootouts between rival drug trafficking organizations as well as between the Mexican soldiers and drug traffikcers.
