Far-right and anti-fascist protesters clashed during a rally commemorating the victims of the Barcelona terror attack. The far-right protesters marched along Las Ramblas boulevard shouting slogans against migrants and Muslims. Police tried to separate them from counter-protesters gathered a few hundred meters away. But they could not prevent physical fights between the groups. On August 17, a van plowed into crowds at Las Ramblas, killing 14 and injuring many more.
