METZ, France (AP) _ Gallo-Roman ruins including some 400 tombs have been unearthed at six sites in eastern France, officials said today.

The Culture Ministry's Moselle office said the tombs excavated outside Sarrebourg dated from 400-800 B.C. Archaeologists also uncovered ruins from a chapel and several primitive houses, including one which might be from the Iron Age, which began in Europe in 1000 B.C.

The ruins were first spotted by road workers, who contacted authorities. Excavations at the site, about 270 miles east of Paris, are to continue until September.
