Shia muslims are introduced as restrict and dangerous people in media. However, they never attack a country or nation and they never had intention to do so. Search " Shia Muslims" in google images , you will see how much negative pobliticize exist against them. You will read so many lies about them. Its just to make you persuaded that "Shia Muslims should be killed and ignored as they are dangerous". Vahhabi people (lets NOT call them Muslims) think that if they kill 6 Shia and they cut their heads God will send them to Heaven. Iranians are Shia Muslims and Saudi people are mainly Vahhbi, thats why USA backs them.
First thing is first, there have been notice about Saudis and foreigners locking themselves at home since we are under attack from daesh (the people who cut other head thinking they will go to heaven..They kill all Muslims(sunni and shiaa ) and non-muslims) and second Saudi is not fighting Yemen.. It is helping Yemen to get rid of rebels. I hope you get your facts straight before blaming a country.
