Foreign ministers of the Group of Seven, or G7, countries on Monday called for a "world without nuclear weapons" in what was called the "Hiroshima Declaration", reported AFP. This was after the ministers of seven of the world's advanced economies – the United States, the United Kingdom, Canada, France, Germany, Italy and Japan – convened in Hiroshima and laid wreaths at a war memorial for the 140,000 victims of the 1945 atomic bombing of the Japanese city by the US. John Kerry also became the first US secretary of state to visit Hiroshima and pay his respects at the memorial, reported Reuters.

A statement released by the group said, "We reaffirm our commitment to seeking a safer world for all and to creating the conditions for a world without nuclear weapons in a way that promotes international stability. This task is made more complex by the deteriorating security environment in a number of regions, such as Syria and Ukraine, and, in particular by North Korea's repeated provocations."
