New York Times:

LAGOS/ANTALYA, Turkey (Reuters) — OPEC may need to intervene to balance the oil market if prices fall further, Nigeria said on Wednesday, making it the latest country in the exporters’ group to float the prospect of supply curbs.
Nigeria joins Libya, Iran and Iraq, fellow members of the Organization of the Petroleum Exporting Countries, in expressing concern this week about the impact of the financial crisis on the oil market.
“There may be a need to intervene to balance the market, if the price slide seemingly predicted on demand and over-supply continues,” Nigerian Oil Minister Odein Ajumogobia told Reuters.
