The Saudi news site "Elaf" recently reported from a "well-informed western source" that Spain spotted a squadron of fighter jets on their way to Morocco.
According to the source, the planes flew in the airspace of Morocco and performed exercises and mock attacks. Then they entered the territory of several countries - initially Algeria and then penetrated radars in North Africa and Europe. None of the countries, with the exception of Spain, announced the presence of the planes.
Elaf added that the planes practiced attacks on many targets at the same time, and it seems that they trained on a distant target scenario. The website concludes that the exercise was intended to prepare for an attack on Iran.
