BARCELONA, Spain -- Hundreds of thousands of peace marchers flooded the heart of Barcelona on Saturday, shouting "I'm not afraid" -- a public rejection of violence after extremist attacks that killed 15 people, Spain's deadliest attack in more than a decade.
Emergency workers, taxi drivers, police and other citizens who helped immediately after the Aug. 17 attack in the city's famed Las Ramblas boulevard led the march. They carried a streetwide banner with black capital letters reading "No Tinc Por," which means "I'm not afraid" in the Catalan language.
The phrase has grown from a spontaneous civic answer to violence into a slogan that Spain's entire political class has embraced.
Spain's central, regional and local authorities tried to send an image of unity Saturday by walking behind emergency workers, despite earlier criticism that national and regional authorities had not shared information about the attackers well enough with each other.
In a first for a Spanish monarch, King Felipe VI joined a public demonstration, along with Prime Minister Mariano Rajoy and other Spanish and Catalan regional officials.
Still, some citizens whistled their displeasure as authorities passed by. Some of those citizens held banners criticizing the king's role in promoting military exports to Saudi Arabia.
Barcelona police said about 500,000 people showed up to the march Saturday.
The Islamic State extremist group has claimed the two vehicle attacks -- one in Barcelona and one hours later in the coastal town of Cambrils -- that left 15 dead and more than 120 wounded. The investigation into the Islamic extremist cell behind the attacks has shown that the group planned even more deadly carnage but accidentally blew up a house in Alcanar where explosives were being built and gas tanks were being stored.
Eight suspects are dead, two are jailed under preliminary charges of terrorism and homicide, and two more were freed by a judge but will remain under investigation.
Medical authorities said Saturday that 22 people wounded in the attacks are still being treated in hospitals. Six of them remain in critical condition.
In the northeastern town of Ripoll, home for many of the attackers, members of the local Muslim community and other residents gathered Saturday in a central square to condemn the deadly attacks. Located at the foothills of the Pyrenees, the town is where most of the suspects came under the influence of a radical imam, investigators say.
The sister of two of the accused extremists gave an emotional speech thanking her neighbors for the support shown to Muslim families in Ripoll.
"We share the same grief and the [need] for an understanding of what happened," said Hafida Oukabir, whose younger brother Moussa was shot dead by police in Cambrils and whose elder brother Driss is in custody facing terrorism charges. "We must all work together to stop this from ever happening again."
Her sobbing speech was met with applause.
