Oil looms large over world stage

The price of oil, one of 2005’s biggest stories, is forcing its way back into the headlines as a political row with Iran threatens to interrupt supplies.

Crude oil prices have rallied in recent weeks as concerns over Iran’s nuclear ambitions have escalated.
Iran has been threatened with referral to the United Nations for restarting its nuclear programme, and there are fears that sanctions may be imposed.

As this unfolds, problems with Nigerian supply have also pushed prices higher.
