Catalan independence: Thousands rally at campaign launch

Pro-independence Catalans have held a rally in Barcelona, on Catalonia's national day.

The event marked the start of the separatists' campaign ahead of Catalonia's regional elections this month.

The Together For Yes campaign says if it wins a majority in the regional assembly it will push through plans for an independent Catalan state but the Spanish government has promised to block any such move.

Tom Burridge joined the crowds on the streets.
