I had my camera nearby and I took video & photos. The UFOs were moving from southwest to northeast and the velocity was variable.

They had metallic texture in black and differents shapes. They moved in groups and some of them changed the shape of their own structure. The distance was about 50 meters.

The sighting was near to the town center and was not near to the airport of any kind of military base. I didn't see any aircraft in the area or any type of exhaust coming from the objects.
