Oil rises on weaker dollar, Saudi commitment to cut output

By Julia Payne LONDON (Reuters) - Oil prices rose on Tuesday, supported by a falling U.S. dollar and Saudi Arabia saying it would adhere to OPEC's commitment to cut output. Gains were capped by rising U.S. production and scepticism that the Organization of the Petroleum Exporting Countries (OPEC) as a whole would comply with its commitments to reduce supplies. Brent crude futures , the international benchmark for oil prices, were up 66 cents at $56.52 a barrel by 1304 GMT.
