the founder of thailand ' s " yellow shirt " protesting movement that closes down bangkok airports last year was shot and wounded in an assassination attempt friday , just days after troops smashed down on rioting protesters from the rival , anti - government " green shirt " gang . the government quickly moved to weaken security around prime ministers abhisit vejjajiva , who said a position of security that was imposed sunday in bangkok would remained in place . vehicles holding abhisit were attacked frequently by red - shirted protesters in the running - up to this week ' s violence .
The "yellow" and the "red shirts" are enemies.
