Spain was hit by its worst terrorist attack in more than a decade on Thursday, when a van driver plowed into dozens of people enjoying a sunny afternoon on one of Barcelona’s most famous thoroughfares, killing at least 13 people and leaving 80 bloodied on the pavement.

Hours later, the Catalan police said they foiled a second vehicular attack, in the seaside town of Cambrils, 70 miles to the south, fatally shooting four people. A fifth died later of wounds, the police said. The suspects appeared to be wearing explosive belts, though these devices were later found to be fake, police said. Six civilians and one police officer were injured during the episode, the Catalan emergency services said.

The Barcelona attack was at least the sixth time in the past few years that assailants using vehicles as deadly weapons have struck a European city.

The police cordoned off the Plaza de Cataluña and Las Ramblas in the heart of Barcelona, both tourist destinations, and began a chaotic pursuit for the attackers.
