Self-proclaimed anarchists stormed the Spanish embassy in Athens today.
They scattered leaflets in favour of Catalonian independence, reading "Solidarity is the weapon of the people", and "No Pasaran", a leftist slogan from the Spanish Civil War.
The demonstrators, from a group known as Rouvikonas, also unfurled a pro-independence banner from the embassy roof.
The embassy staff briefly evacuated the premises, leaving only a few diplomats inside. There were no reports of damage or injuries.
Greek police detained 19 people.
The banner was taken down after the protesters were detained
