Barcelona
It's one of the biggest pro-unity rallies amid Catalonia's independence crisis.
The government voted to strip Catalonia of its autonomy less than an hour after the region declared independence.
Catalonia declared independence on Friday. Minutes later, Spain imposed direct rule.
WHAT'S HAPPENING
Carles Puigdemont said he had not received enough guarantees that the move would stop Spain imposing direct rule.
Metro stations were closed in Barcleona as state workers walked out across Catalonia.
Authorities say more than 460 people have been injured.
The autonomous state is set to hold an secession vote on Sunday, which Madrid has deemed “illegal and undemocratic.”
