MADRID — A train traveling in northwestern Spain has derailed, toppling passenger cars on their sides and leaving at least one torn open as smoke rose into the air.

It was not immediately clear how many people were injured or if any had died.

Spanish state television showed images of the accident on high-speed tracks near the train station in Santiago de Compostola, 95 kilometers (60 miles) south of El Ferrol.

The train was headed to El Ferrol from Madrid on Wednesday.

Officials at the Interior Ministry or with Spain’s state-owned Renfe passenger train company and the Adif rail infrastructure authority did not immediately answer telephone calls or return messages seeking comment.
