Vienna - The price for crude oil produced by the Organization of the Petroleum Exporting Countries (OPEC) was at a new record high at the beginning of the week, OPEC said Tuesday.

One barrel (159 litres) of crude from OPEC's reference basket of 13 crudes stood at 111.66 dollars on Monday, up 1.65 dollars from Friday.

Crude prices, already boosted by the weak US dollar, were also affected by strikes in Scotland and Nigeria as well as unrest in the African country, analysts said. (dpa)
