A 66-year-old woman has died after she was hit by a van while trying to save her dog after it got loose on the M4. The pet was also killed after running on to the motorway from its owner’s Volkswagen Golf at about 18:20 BST on Friday near Cardiff Gate services. South Wales Police said the westbound carriageway was closed for five hours between junctions 29 and 32 after the woman was hit by a Ford Transit. She was pronounced dead at the scene. The woman’s family is being supported by a family liaison officer.
