The upthread HN claim was that this "was an attack".

The Xitter claim was that:

  Moroccan traffic police keeps directing thousands of illegal migrants toward the Spanish border fence in Ceuta.

  This is a state-orchestrated invasion of Spain.

The video shows a small number of people on a small number of truck beds calmly going about a roundabout.

No visible attack, no proof that the people visible are "thousands of illegal migrants" nor of where they are or where they are headed.
