An Italian military helicopter carrying up to eight people crashed Thursday in northeastern France, killing all on board, local officials said.

The helicopter, one of two on its way from France to Belgium, went down about 4:30 p.m. in the Meuse region between the towns of Lisles-en-Barrois and Vaubecourt, police and officials said.

The second helicopter safely reached its destination, said Alexandra Petit, communications official for the prefecture of the Meuse region.

She said it remained unclear whether the aircraft carried seven or eight people.

In Rome, Italian Air Force Sgt. Emiliano Conte said the search-and-rescue helicopter, an HH3F, had been conducting a training exercise over France and Belgium.
