TARRAGONA, Spain, October 7 (Reuters): Protesters calling for Catalan independence kicked off Spain's bi-annual human towers building competition on Sunday which is being held for the first time since Catalonia's failed 2017 independence referendum. Though the competition is not an official pro-independence event, human towers building is a deep-rooted tradition of the Catalan culture where participants are considered either supporters of or in favour of secession from Spain. The event, which drew 6,000 spectators in the northeastern city of Tarragona, comes almost a week after tensions flared up again with thousands marching in Barcelona to mark the anniversary of the Oct. 1 2017 referendum. Opinion polls in Catalonia show a relatively even split between those who favour remaining in Spain and those wanting to secede. People carried a huge Esteleda, the Catalan separatist flag, inside the Tarraco Arena Plaça in Tarragona when the finals for the competition started with the official national anthem of Catalonia 'Els Segadors' (The Reapers).
