South Korea's new President Moon Jae-In was sworn in on Wednesday, just a day after a landslide election victory, beginning his term in office facing multiple challenges from the aftermath of a huge corruption scandal to tensions with the North.

"I do solemnly swear before the people that I will faithfully execute the duties of the President," Moon declared before legislators in the National Assembly building in Seoul.
