Oil prices gained around two per cent for the week ended on Saturday as Iraq voiced support for OPEC’s oil cuts ahead of a meeting in two weeks and as some speculators covered massive short positions ahead of weekend uncertainty. Still, prices settled with weekly losses of 4 per cent, their third straight weekly decline. Brent ended this week at 81 dollars and 43 cents per barrel, while the US crude closed at 77 dollars 17 cents a barrel.
