Authorities in Saudi Arabia have released the brother of a billionaire prince who was in detention for 11 months. Saudi Prince Khaled bin Talal is believed to have been in detention since January. The prince is the brother of Prince Alwaleed bin Talal - one of a group of royal family members and businessmen who were held in the lavish Ritz Carlton in Riyadh last year as part of an anti-corruption purge. Alwaleed, who Forbes estimated had a personal fortune of $17 billion, was released almost three months later. The group paid over $100 billion in settlements for what Saudi authorities said were corruption charges. But critics outside Saudi Arabia said the wave of arrests were part of Crown Prince Mohammed bin Salman's efforts to silence potential opposition to his leadership. Khaled's release comes as Saudi Arabia faces increased scrutiny from Western powers over the killing of journalist Jamal Khashoggi, at the Saudi consulate in Istanbul last month. Khashoggi, 59, a royal court insider-turned-critic, was killed after entering the consulate on October 2 to obtain paperwork for his upcoming marriage. Saudi officials have presented shifting stories about Khashoggi's fate, initially denying any knowledge of his death, then arguing that a group of rogue operators, many of whom belong to Saudi Crown Prince Mohammed bin Salman's inner circle, was responsible for his killing.
