Yemen's Hadi takes oath as new president SANAA (Reuters) - Abd-Rabbu Mansour Hadi took the constitutional oath to become Yemen's new president on Saturday, after a vote this week where he stood as the sole candidate to replace Ali Abdullah Saleh in a U.S.-backed power transfer deal brokered by Gulf neighbors. The election, where more than 60 percent of eligible voters had taken part, makes Saleh the fourth Arab autocrat to be removed from power in more than a year of mass uprisings and war that have redrawn the political map of the Middle East. Hadi's inauguration is scheduled for Monday, which Saleh is to attend. Saleh returned to Yemen on Friday after seeking treatment in the United States for injuries suffered in a assassination attempt last year. Reporting by Joseph Logan
