You would not know about this in US media because Gulf lobbies don't want to talk about it, and journalists who are tied to the Gulf lobbies in DC are not under instruction to divulge it. Basically, the relations between Qatar and Saudi Arabia are getting worse and worse, and the relationship between Oman and Saudi Arabia have always been bad (yesterday the Omani minister of state for foreign affairs said that Saudi Arabia went to war in Yemen without consulting "with us" and yet "wants us to save it"), and the relationship between Saudi Arabia and Egypt are worsening. There has been a campaign by young Saudis (clearly orchestrated by the chief of social media in Saudi intelligence apparatus) against Aljazeera because it refers to Saudi soldiers killed in Yemen as "dead" and not as "martyrs".
