The Suspects in the Attacks in Barcelona and Cambrils Were Planning One or More Bigger Attacks

The suspects in the attacks in Barcelona and Cambrils were planning one or more bigger attacks than those that were carried out, police say, reported BBC. 

Catalonia's police chief said blasts in a town south of Barcelona on Wednesday deprived the plotters of bomb material, forcing them to carry out simpler attacks using vehicles to ram crowds.

A manhunt is under way for Moussa Oukabir, 18, suspected of carrying out Thursday's Barcelona attack.

Thirteen people died in Las Ramblas.

Moussa Oukabir is suspected of using his brother's documents to rent the van that mowed down people on the famous boulevard.

Hours later, police killed five suspected jihadists in a second vehicle attack in the town of Cambrils. A woman injured in that attack died later.

Police said the men killed in Cambrils were linked to the Barcelona attack, which the Islamic State (IS) group said it had carried out.

Spanish Prime Minister Mariano Rajoy condemned what he called a "jihadist attack" in Barcelona. He has announced three days of national mourning and a minute's silence was held at noon (10:00 GMT) on Friday.

Police say they are investigating the theory that the attacks were being prepared over a substantial period of time in a private house in Alcanar, a small town south of Barcelona.

Explosions ripped through the building on Wednesday evening, apparently caused by exploding gas canisters. One person was killed.

The explosives were being prepared for use in one or more attacks in Barcelona, police said.

Catalan Police Chief Josep Lluis Trapero said the actual attacks in Barcelona and Cambrils were "rudimentary" in comparison.
