The multi-platform WMD-We Must Disarm campaign began on 13 June and issues new messages on reasons for nuclear disarmament and non-proliferation daily over Twitter.

United Nations Secretary-General Ban Ki-moon launched the campaign by tweeting the first week’s messages. He will issue a special video message on 6 August, the anniversary of the atomic bomb strike on Hiroshima.

**How to Participate**

The United Nations is looking for short videos from anyone, regardless of skill or experience, to submit their work by Thursday, 10 September. All entries should be on the subject of nuclear disarmament and/or non-proliferation and no longer than three minutes in length. Films should support the Secretary-General’s multi-platform WMD-We Must Disarm campaign. Participants should upload their films on YouTube and send a link to the film to Melanie Nolte at nolte@un.org.

Submissions containing obscene or offensive language or imagery will not be considered for the competition, nor will overtly political references to any particular country. A panel of United Nations staff and partner organizations involved with nuclear disarmament and non-proliferation will be the judges.
