Oil prices were little changed in early trading on Tuesday as global growth concerns, U.S. tariffs and Russia-Ukraine ceasefire talks offset increased instability in the Middle East that could impact supply.
Brent futures ticked up 10 cents, or 0.14%, to $71.17 a barrel by 0135 GMT, while U.S. West Texas Intermediate crude futures rose 7 cents, or 0.1%, to $67.65 a barrel.
