Iran accused Europeans on Monday of waging "psychological warfare" after the EU banned imports of Iranian oil, joining the United States in new sanctions aimed at preventing Tehran from getting nuclear weapons.
The sanctions ban all new oil contracts with Iran and freeze the assets of Iran's central bank in the EU.
The EU currently buys about 20% of Iran's oil exports.
"European officials and other countries which are under America's political pressure... should consider their national interests and not deprive themselves of Iran's oil to help US officials achieve their secret aims," Mr Mehmanparast added.
