The Spanish police launched an operation to transfer thousands of migrants to a new camp in Saba.
But during the move to the camp with a capacity of 1,700 people, the crowd rushed past the police lines, and they resorted to aerial firing.
In the published videos of the police clash with the immigrants, the sound of gunshots is heard.
Most of the 72,000 migrants who crossed the Moroccan border into Spain in July have returned, but it is estimated that more than 13,000 of them are still at this port in North Africa.
According to the Spanish state news agency, the police operation began on Friday, September 18, at 7:00 a.m. local time, and so far more than three thousand migrants have been transferred.
The Spanish news agency reported that more than 170 police officers, including experts in drone training, were deployed and the situation "quickly came under control" and the operation continued.
This operation is part of the government's effort to concentrate the immigrants in centers where their situation can be identified and treated. The influx of migrants to the Spanish border has put the issue of EU border security and immigration control at the center of attention.
