Oil prices down on Tuesday as resilient Middle Eastern crude exports and a G7 emergency stockpile release eased supply concerns, though attacks by Yemen's Houthis on Saudi targets kept traders wary of risks to Gulf supplies.
Brent crude futures lost 4 cents to $100.28 a barrel by 0003 GMT, while US West Texas Intermediate crude futures fell 11 cents, or 0.1%, to $89.33 a barrel.
