TEHRAN (IRNA) -- First Vice-President Parviz Davudi here Sunday criticized the West's dual standards in dealing with Iran's nuclear issue.

Meanwhile, he regretted the dual standard witnessed in international bodies.

The statement was part of the speech delivered at the ceremony marking the World Health Day in Tehran.

"Big powers producing atomic bombs justify that their production and testing is required to safeguard peace and security of the weak countries.

"This is while, the negative consequences of atomic bombs and their impact on the people of the regions where they are applied remain for centuries," he added.

Davudi said that international organizations chant the slogan of democracy, human rights and security, while they have prevented the scientific and peaceful measures in a country (Iran) and they have issued resolutions against it.

"This creates a type of psychological insecurity, which is against the policy of world health and the World Health Organization (WHO) should tackle the issue," he added.

The first vice-president urged that WHO should stand up to such moves and use of nuclear weapons as well as their producers and users.
