Mexican federal police momentarily crossed the Rio Grande into the United States on Thursday morning in an incursion under investigation by both countries, a U.S. Border Patrol spokesman said.
The incursion occurred east of the Zaragoza Bridge while three hunters were on the U.S. side on the first day of dove season.
Channel 9-KTSM reported a relative of the hunters told the station that gunmen in Mexico fired at the hunters and that the gunmen crossed the border and stole their chairs.
Border Patrol spokesman Doug Mosier said border agents and Texas Parks and Wildlife officers responded immediately. There were no reported injuries.
Agents arriving at the scene saw Mexican federal police crossing the river back into Mexico after they had been on the U.S. side, Mosier said.
