CNN —Four US citizens were assaulted and kidnapped after crossing the border into northeastern Mexico on Friday, according to the FBI, which is working to locate the missing Americans. Soon after the US citizens drove into the border city of Matamoros, Mexico, on Friday they were fired upon by unidentified gunmen, a release from the FBI in San Antonio said. The US citizens were driving a white minivan with North Carolina license plates, according to the FBI. Anyone with information related to the incident is encouraged to call the FBI San Antonio Division or submit a tip online. Matamoros is located in the Mexican state of Tamaulipas, for which the US State Department has issued a “Level 4: Do Not Travel” advisory for US citizens, citing crime and kidnapping.
