Kim Jong-un had paid a visit to the Pyongyang Cosmetics Factory together with his wife Ri Sol-ju and sister Kim Yo-jong.

Kim apparently also said during the outing that the products produced there help North Korean women "be more attractive".More news: PM Modi accuses Congress of supporting those who want Azadi in Kashmir

Two of seven North Korean agents were arrested over the alleged plot to kill Kim Han Sol, whose father Kim Jong Nam was assassinated in Malaysia earlier this year, the newspaper said, citing an unidentified person familiar with North Korean issues.
