 "Oil prices up 2% on hopes of OPEC output cut")
Oil prices rose around 2% on Tuesday, bouncing back from multi-month lows on optimism that OPEC will agree later this month to cut production to reduce a supply glut. North Sea Brent crude oil was up 75 cents a barrel at $45.18 by 0915 GMT after hitting a three-month low of $43.57 on Monday.
US light crude oil rose $1.11 a barrel, or 2.5%, to a high of $44.43 before easing to $44.30. It reached a three-month low of $42.20 on Monday.
Oil producers in the Organisation of the Petroleum Exporting Countries are due to meet on Nov 30 to agree to limit output. An outline deal was reached in September but negotiations on the detail are proving difficult, officials say.

Saudi Arabia's energy minister has said it is imperative OPEC reach a consensus on a deal to curb production, Algeria's state news agency APS said on Sunday.
"Reports of a diplomatic push by OPEC to strike a deal are supporting the markets," said Tamas Varga, oil analyst at London brokerage PVM Oil Associates. "The rally could last a little while but the underlying fundamental picture is still bearish."
