Spanish police have fired rubber bullets and baton-charged protesters attending a rally against austerity, according to reports.
The clashes occurred as protesters tried to tear down metal barriers blocking access to the parliament in Madrid.
The BBC's Tom Burridge visited the scene and said that the demonstration had "more of an edge" than previous protests.
He also described "an eerie feeling" on the streets of the Spanish capital, with the "police wary that this could have turned into something bigger".
