SEOUL, South Korea - North Korea has acknowledged the purge of leader Kim Jong Un's powerful uncle for "anti-state" acts and "double dealing."

The lengthy dispatch Monday from state media says Jang Song Thaek formed a faction in the ruling party "by creating an illusion about him" and distorting and weakening party goals. South Korean intelligence officials have said two of Jang's aides were executed for corruption.

Images of Jang have been removed from an official state TV documentary.
