Protesters in Madrid have targeted a branch on Spanish bank Santander, smashing windows and scrawling graffiti blaming the bank for the financial woes of the country.
Main roads in the Spanish capital remain closed with multiple fires raging as firefighters try and keep up with protesters.
There were angry clashes in some European cities today as hundreds of thousands of people took part in anti-austerity protests.
Strikes and rallies took place in Spain, Portugal, Greece, Italy and Belgium:
Hundreds of thousands of protesters are on the streets of Madrid tonight. Their message to their leaders is that not only is austerity not working, but that it's making things worse.
That message is supported by dreadful economic figures today that show accelerating recession in southern Europe and big falls in manufacturing output.
All the focus, certainly in Brussels and Berlin, is on saving the Euro and avoiding the catastrophe that they think would follow a collapse of the currency.
But leaders in cities like Madrid have to see what their people are doing and saying. Much more of protests like today's, and this country could become ungovernable.
Left-leaning Spanish news organisation La Tuerka claims its photographer was "assaulted and arrested by police" at a protest march in Madrid.
It uploaded this footage of the incident:
Tens of thousands of people are out on the streets of Barcelona protesting against the austerity cuts.
There are lots of families, students and union members. Plenty of firecrackers are going off but everything appears peaceful.
