to pro-independence movement called for a general strike. However, major trade unions (UGT and CCOO) did not endorse the event as well as representatives of the latter contested its very nature as "strike". Five peaceful marches converged on Barcelona's city center, essentially bringing the city to a halt. Protesters further blocked the road on the French-Spanish border. At least 20 other major roads were also blocked. Clashes nevertheless took place, with masked protesters confronting riot police by throwing stones and setting alight rubbish bins. 25,000 university students joined in the protest movement by declaring a peaceful student strike. As a result of the strike, trains and metro lines saw a reduction to 33% of their usual capacity, while buses saw a reduction to 25-50% of their usual capacity.
