Vienna - The basket price of the Organization of the Petroleum Exporting Countries (OPEC) rose slightly Tuesday but stayed below the 70-dollar mark, the group announced Wednesday.

One barrel (159 litres) of OPEC-produced crude oil settled at 69.68 dollars Tuesday, inching upwards from 69.24 dollars on the previous day.

The 12 member countries of the Vienna-based cartel produce some 34 per cent of the world's oil. (dpa)
