Iran's official Press TV says the country plans to ban imports from 100 European companies as part of Tehran's pre-emptive retaliation against an EU embargo that is to go into effect in July.
The station reported on Wednesday that Tehran took the measure to punish European countries for sanctions imposed by the bloc on Iran over its controversial nuclear programme. It did not say which companies or countries would be singled out by the import ban.
Iran's media reported that it has cut sales of crude oil to Germany, Spain and Greece over the last two days.
Tehran had already stopped sales to Britain and France, and says it may also cut oil exports to Italy. The West suspects Tehran of pursuing nuclear weapons, a charge Iran denies.
