Roads in Catalonia were brought to a standstill on Wednesday as pro-independence demonstrators striked in protest against the Spanish government's arrest and detention of Catalan leaders.
The strike was called by the CSC union and was supported by the Asamblea Nacional Catalana (ANC) and Omnium Cultural, Reuters reported.
Sitting on the road, protesters called for "freedom for political prisoners".
Senior figures within the Catalan government were arrested and detained accused of sedition and rebellion over independence referendum held last month.
