Javed Faizal, a member of Maldives' U.N. Mission, said Friday that Iran announced its decision at a meeting of the Asia group, which was preparing its slate of candidates for next month's vote on new rights council members.
Iran was heavily criticized in February at the 47-member council's first review over its handling of human rights.
Peggy Hicks, global advocacy director for Human Rights Watch, praised Iran's decision to withdraw as a "good thing."
The Iranian mission did not immediately respond to requests for comment.
