BREAKING: Barcelona suspect killed in shootout with police on outskirts of city

One of the suspects of today's horrific car-attack in Barcelona has been killed during a police shootout as he attempted to flee the Spanish city.

Local newspaper La Vanguardia says the suspected terrorist died after fleeing central Barcelona. He allegedly drove through a police barricade injuring at least one officer before being caught in the town of Sant Just Desvern. It's now believed that he was killed in the ensuing shootout.

Mariano Rajoy, the Spanish Prime Minister, said that there would be "maximum coordination to arrest the attackers, reinforce security and attend to all those affected".

People have been told to stay indoors, and Barcelona police are treating the attack as terrorism, though any relation to specific groups is unproven. This isn't Spain's first brush with terror. In 2004, an enormous attack killed 192 people in a subway. Al-Qaeda was responsible for the attack.

The total number of attackers is unknown, with an additional suspect named Driss Oukabir involved in the attack. One person has been detained, and another shot by police. It is still unclear how Oukabir relates to these incidents.
