Oct. 15 (UPI) -- Police in Spain are preparing to square off with protesters again Tuesday after the country's Supreme Court sentenced nine Catalonia separatists to up to 13 years in prison on sedition charges.
Catalonia independence demonstrators blocked passenger trains, bogged down busy roadways and caused more than 100 flights to be canceled Monday. Protesters gathering at Barcelona's main airport Tuesday threatened international American Airlines flights to New York, Miami, Chicago and Philadelphia.
