North Korea's state media says the country's leader, Kim Jong Un, has been elected as general secretary of the ruling Workers' Party. The post was held by his late father, Kim Jong Il.
The Monday edition of the party's newspaper, Rodong Sinmun, says the decision was made on the sixth day of a party congress in Pyongyang on Sunday.
It quotes the congress as saying in a statement that it fully supported a proposal to promote Kim to general secretary.
The statement also says Kim has completed plans to build up North Korea's nuclear capabilities and turned the country into a world military power.
At a party congress five years ago, Kim took up the newly-created post of party chairman.
