Four United States citizens have been kidnapped after a group of gunmen opened fire on their vehicle in the border city of Matamoros just south of the United States.
The FBI said the group had entered Matamoros through Brownsville, Texas, on Friday. They had travelled in a white minivan with North Carolina license plates.
The vehicle came under fire shortly after entering Mexican territory, according to an investigation being done by the San Antonio FBI office.
‘All four Americans were placed in a vehicle and taken from the scene by armed men,’ said the office.
