Vienna - The basket price of the Organization of the Petroleum Exporting Countries (OPEC) eased to 66.41 dollars at midweek, the group announced Thursday.

In its first decrease since May 25, the price of OPEC-produced crude oil shed 0.46 dollars on Wednesday.

The 12 member countries of the Vienna-based cartel produce more than a third of the world's crude oil. (dpa)
