PARIS (AP) — French authorities backtracked Friday, reducing the death toll from six children to least four after a regional train sliced open a school bus in southern France. Authorities in the Pyrenees-Orientales region said their statement earlier in the day that six children had died was not confirmed in the horrific crash at a crossing close to the Spanish border. Four children aged 12 or 13 died Thursday in the collision, and 18 others and the bus driver were injured.
