Tens of thousands of people gathered in Valencia to protest the government's response to recent deadly floods.
Demonstrators, calling for the resignation of regional head Carlos Mazón, chanted "we are stained with mud, you are stained with blood" as they marched through the streets.
More than 200 people lost their lives in the floods, which were caused by heavy rainfall in October, and 80 remain missing.
Protesters accused local authorities of delaying flood warnings, leading to greater loss of life and property damage.
