A Palestinian flag flies as U.S. Jewish musician Matisyahu performs on stage during the Rototom Sunsplash festival in Benicassim, August 23, 2015. The Spanish reggae festival, bowing to an international outcry, on Wednesday reversed its decision to cancel an invitation to Matisyahu because he had failed to spell out his views on Palestinian statehood.
