Iran nears first big Western energy deal

Total CEO: We have a long history with Iran

Iran is on the brink of clinching billions of dollars of Western investment in its oil and gas industry, the first since sanctions were lifted earlier this year.

Total, a French energy company with a long history in Iran, said a deal could happen within days. And a source at the Iranian energy ministry said a document setting out the key terms of a proposed agreement would be signed Tuesday in Tehran.
