Saudi-UAE conflict

"Relations between Saudi Arabia and the United Arab Emirates have been strained in the six months since Saudi Interior Minister Prince Nayef Bin Abdelaziz was appointed second deputy premier, effectively catapulting him to become next in line to rule, while Crown Prince Sultan Bin Abdelaziz, who is 84, has been convalescing in the United States and Morocco (GSN 860/14, 858/1; 857/7). Many believe that due to his poor health and advanced age, Sultan is unlikely to succeed King Abdullah Bin Abdelaziz. If Nayef is next in line to the throne, the UAE has a dilemma because he has been party to most of the major bilateral diplomatic incidents for nearly four decades. Nayef, who is 76, has served in the Saudi Ministry of Interior (MoI) since 1970." (thanks Sultan)
