Several people are understood to be wounded after being struck by a van in the Spanish town of Cambrils, prior to it being intercepted by police.
The van attackers in Cambrils struck and wounded several people before they were intercepted, Spanish media report.
A spokeswoman for the Catalan police said that officers have killed four attackers in Cambrils, south of Barcelona, and another is seriously injured following an operation there against what authorities called a terrorist attack.
The incident appear to be an attempt to replicate the attack in the nearby city of Barcelona earlier, where thirteen people died and dozens were injured when a van ploughed into crowds in Barcelona’s Las Ramblas area on Thursday afternoon.
Spain’s Prime Minister Mariano Rajoy said the events in Barcelona were a “jihadist attack”. Islamic State militants claimed responsibility for the attack online.
The two attacks are thought to be linked, as well as an explosion at a house in another town in Catalonia on Wednesday night.
