Mexican soldiers probed after six killed on highway

Mexican prosecutors have opened an investigation into a group of soldiers after six people were shot dead Monday on a highway in Tamaulipas, a violence‑plagued state along the U.S. border. Mexico’s Defense Ministry said troops fired after a white pickup allegedly tried to ram an army vehicle; prosecutors say five died at the scene and a sixth died en route to hospital. The probe comes amid broader scrutiny of security‑force actions in cartel‑dominated border cities and follows prior convictions of soldiers for civilian killings in nearby Nuevo Laredo.
