(AP) MADRID - Spaniards angered by increasingly grim economic prospects and unemployment hitting one out of every four citizens protested in droves Saturday in the nation's largest cities, marking the one-year anniversary of a spontaneous movement that inspired similar anti-authority demonstrations across the planet.
The country's Interior Ministry said 72,000 people marched against the government's tough austerity measures in Madrid, Barcelona and six other large cities but protesters claimed the turnout was much higher.
The epicenter of the protest was in the capital of Madrid, where at least 30,000 people flooded into the central Puerta del Sol plaza in the evening, vowing to stay put for three days.
Authorities warned they wouldn't allow anyone to camp out overnight as protesters did last year but the demonstrators stayed put after a midnight deadline to leave and more than 2,000 riot police on duty made no immediate effort to force them out.
"I'm here to defend the rights that we're losing and for the young people who have it so tough," said 57-year-old middle school teacher Roberto Alonso. "They're better educated than ever. But they don't have work. They don't have anything. They're behind and they'll stay that way."
At least 22,000 people demonstrated in Barcelona, Spain's second largest city. Marches were also held in Bilbao, Malaga and Seville, and sympathizers from other countries held protests across Europe.
The protests began May 15 last year and drew hundreds of thousands of people calling themselves the Indignant Movement. The demonstrations spread across Spain and Europe as anti-austerity sentiment grew.
Spain is in dire economic straits, prompting fears it may need a bailout similar to those requested by Greece, Ireland and Portugal. It is in recession, and unemployment stands at almost 25 percent the highest among the 17 countries using the euro. One in two Spaniards under the age of 25 are out of work.
Prime Minister Mariano Rajoy's conservative government has enacted deep spending cuts to reduce the national debt, but many people blame those measures for deepening families' financial plight.
Javier Colilla, a 27-year old university student, said he showed up to protest in Madrid because Spain's economic situation seems like it will spiral into chaos.
"We've had this crisis for four years, but it feels like it's just starting," the fine arts major said.
Colilla lives with his parents, sees zero prospect of getting a menial job after graduation and thinks he may never be able to buy an apartment.
"Right now I'm thinking my best option will be to go to Germany where I can wash dishes, make a little money and learn German," he said. "The prospects of getting a job in Spain are practically inexistent."
