According to the website of Radio France and the New York times, some French missiles were found at a base near Haftar in Libya. The fact goes back to last June when some model "Javelin" missiles had been found in a warehouse belonging to the rebel general by the forces of the national union government of Libya (GNA).
The news was confirmed this morning by the French government, specifying that, although they recognized the property, they would never have been supplied to Haftar and that they are in any case out-of-use missiles that had to be destroyed.
