Spain has kept its national security alert to one step below maximum since July 2015, following violent attacks in France and elsewhere.
In August 2016, as thousands of revellers packed a pedestrian esplanade in Nice to mark Bastille Day in France, a French-Tunisian man careened through the crowd in a deliberate attack, leaving almost 90 people dead.
French investigators say the attacker was inspired by ISIS propaganda on the internet, but had no links to the terror group.
