Spain erupted in riots and tear gas.
Riots hit Barcelona and Madrid following a general strike for affordable housing. In the capital, about 120 thousand people took to the streets, in Barcelona - about 55 thousand.
After the marches ended, groups of radicals began smashing storefronts, including Apple, H&M and Victoria's Secret, and setting trash cans on fire.
The police used tear gas, rubber bullets and batons. At least 73 people were arrested throughout the country, 18 in Barcelona alone.
