Oil prices fell on Friday as key ministers from the OPEC producers group meeting in Cairo suggested the cartel would wait until next month before announcing any decision to cut output. Organization of Petroleum Exporting Countries ministers are holding consultations in the Egyptian capital this weekend amid speculation they might further reduce production to stem the slide in crude prices. "Here we will prepare some data and maybe the final decision will be in Algeria," Iranian Oil Minister Gholam Hossein Nozari told reporters, referring to a planned extraordinary OPEC meeting in Algeria on December 17.
