IRNA - Iranian Foreign Minister Mohammad Javad Zarif in a Twitter message which was released on the occasion of the International Day of Peace, underlined necessity of international peace and security.

"Say not all are fighting, what use is my lone call for peace? You're not one, but thousands; light your beacon (Rumi-1207-1273)," Zarif wrote translation of a poem from great Iranian poet in his Twitter account.

Each year the International Day of Peace is observed around the world on 21 September. The UN General Assembly has declared this as a day devoted to strengthening the ideals of peace, through observing 24 hours of non-violence and cease-fire.

The International Day of Peace was established in 1981 by the United Nations General Assembly. Two decades later, in 2001, the General Assembly unanimously voted to designate the Day as a period of non-violence and cease-fire.
