Iran is calling for a 30-day oil embargo against Israel's main allies, in response to Israel's military incursions into Palestinian-controlled territories.
In a message to the head of the Organization of the Islamic Conference, Iranian President Mohammad Khatami, called for stopping exports from Islamic oil producing countries to Israel's main allies for one month.
Mr. Khatami said the embargo would be in response to what he called "crimes against humanity" he says were committed by the Israeli army during its military operation in the West Bank.
Ten-days ago Iran's supreme leader, Ayatollah Ali Khamenei, also called for an oil embargo.
Saudi Arabia, the world's largest oil exporter, has rejected the idea of an embargo and says it will remain a reliable, worldwide, supplier.
Iran, second only to Saudi Arabia in the Organization of Petroleum Exporting Countries (OPEC), is not expected to engage in an embargo on its own. Oil revenues account for 80 percent of Iran's hard-currency income.
No Iranian oil has been exported to the United States since 1995, when former President Clinton imposed an embargo against Iranian oil.
Iran's neighbor, Iraq, enforced a unilateral oil export embargo last week.
