the founder of thailand ' s " yellow jacket " protest movement that shut down bangkok airfields last year was injured and wounded in an assassination attempt wednesday , just days after troops fired down on rioting protesters from the rival , anti - government " red shirt " group . the government quickly decided to tighten protection surrounding justice minister abhisit vejjajiva , who said a certificate of emergency that was imposed sunday in bangkok would maintain in place . vehicles carrying abhisit were attacked briefly by red - udd protesters in the run - up to this week ' s uprising .
The "yellow" and the "red shirts" are enemies.
