Oil prices were mixed in choppy trade on Tuesday as disagreement flared within producer cartel OPEC on who should cut how much production in a planned coordinated reduction to prop up prices.
International Brent crude oil futures fell 5 cents to $51.41 per barrel as of 0655 GMT from their last close. U.S. West Texas Intermediate (WTI) crude futures turned positive, gaining 5 cents to $50.57 a barrel, late in the Asia time zone after being negative, falling to a low of $50.37 a barrel, for much of the Asia session. The dollar, which held near nine-month highs against a basket of major currencies, weighed on prices. A strong dollar makes greenback-denominated commodities including oil more expensive for holders of other currencies.
Iraq´s oil minister Jabar Ali al-Luaibi said on Sunday the second-largest producer in the OPEC wanted to be exempt from output curbs as it needed more money to fight Islamic State militants.
