Brent oil rose on Tuesday, hovering at a two-week high, as conflict in South Sudan threatened the country's oil output at a time when production cuts in Libya are already curbing global supply.
South Sudan's production has fallen by 45,000 barrels per day (bpd) to 200,000 bpd after oilfields in Unity state shut down due to fighting. Amid the uncertainty, traders bought back contracts to cover short positions ahead of the Christmas holiday on Wednesday, which drove U.S. and European prices up in light holiday trade.
U.S. gasoline futures supported oil prices, trading up 1.24 percent, after reaching a 15-week high in the previous session. Refinery snags in the United States and striking refinery workers in France thinned supply while demand remains robust.
