Police are clashing with a large group of
Catalan separatists in downtown
Barcelona in a flareup of violence in the restive Spanish region.
Several hundred mostly masked
protesters have surrounded the national
police headquarters in the Catalan city and are throwing bottles and rocks at officers in riot gear.
The clash comes after 350,000 people protested peacefully Saturday against the imprisonment of nine Catalan separatist leaders for their roles in an illegal 2017 secession bid.
