LONDON - Oil prices rose Tuesday, a day after sliding on the strong dollar, but fears over the supply glut kept gains in check before a key producers' meeting next month. The market had tumbled Monday after Federal Reserve boss Janet Yellen indicated a possible US rate hike this year, sending the greenback rallying and making crude more expensive for holders of other currencies. Investors however moved in to pick up bargains on Tuesday. At around 1300 GMT, US benchmark West Texas Intermediate for delivery in October was up 33 cents at $47.31 a barrel.
