Anti-tourism protesters clashed with hotel staff in Barcelona, appearing to fire flares and water pistols in a display of unrest on Sunday 15 June.
The incident was part of a wave of coordinated demonstrations across major European tourist hotspots, aimed at challenging the growing impact of "touristification."
Footage from the protest appears to capture a loud bang, followed by demonstrators spraying hotel staff with water pistols and kicking a flare into a hotel entrance as they marched down the street.
