Recent ballistic missile launches by the Democratic People’s Republic of Korea (DPRK) shows the need for more international dialogue on the nuclear issue.

This Saturday, 6 August, marks 71 years since the world witnessed the destructive power of atomic weapons with the bombing of the Japanese city of Hiroshima during the Second World War.

A second city, Nagasaki, was bombed three days later.

UN Secretary-General Ban Ki-moon said on Saturday that he was "honoured to convey my deepest respect" to all those taking part in the Peace Memorial Ceremony in Hiroshima.

He called on all states to "overcome their differences to galvanize global will for disarmament."
