North Korean leader Kim Jong Un's younger sister is among the officials who won new posts at the country's ruling-party congress.

The state-run Korean Central News Agency reported Tuesday that Kim Yo Jong was named a member of the Workers' Party of Korea's Central Committee during the congress that ended Monday.

Kim Yo Jong has served as a vice department director with the Central Committee, which is among the party's leading bodies. Believed to be in her late 20s, she frequently appears at her brother's public events, standing out amid elderly male officials.
