According to news agency reports, around 70,000 people participated in demonstrations in the capital Madrid. Protesters voiced concerns over rising rents, evictions and the lack of affordable homes.
Demonstrators called on the government to take immediate measures to address the housing crisis and ensure the availability of affordable accommodation.
Protests were also held in Valencia, where clashes were reported between demonstrators and police. Authorities reportedly used tear gas and rubber bullets to disperse protesters.
The protesters warned that they could launch a wider strike if their demands for affordable housing and action to address the housing crisis were not met.
