Prince Nayef bin Abdulaziz al-Saud, newly appointed Crown Prince speaks at an intrerview at the Riyadh Governor\'s Palace, October 29, 2011.  Saudi Arabia named a new crown prince late Thursday: the tough-talking interior minister who is known for cracking down on Islamic militants and resisting moves toward greater openness in the ultraconservative kingdom. Saudi state TV announced the naming of Prince Nayef bin Abdel-Aziz Al Saud as heir to the Saudi throne following the death of the previous second in line, Crown Prince Sultan, last week. Prince Nayef, 78, was also named vice prime minister and will also keep his job as interior minister.
