A driver deliberately plowed a van into pedestrians on one of Spain's busiest streets, Las Ramblas, on Thursday, killing 13 people and wounding more than 80 in what police called a "terrorist attack".
Vehicles have been used as weapons of terror several times over the past year, often by by followers of Daesh, attacking nations in the U.S.-led coalition fighting the extremists in Iraq and Syria.
Daesh's propaganda agency Amaq claimed that "soldiers" from the militant group carried out the attack, according to the Site Intelligence Group which monitors extremist websites.
Police said they had arrested two suspects.
