Oil prices finished Tuesday's session higher after seesawing in choppy trade, as investors weighed the potential for disruptions to crude supply, especially in the Middle East.
Crude futures tumbled nearly 2 percent in the previous session on easing fears that Friday's U.S.-led air strike on Syria would escalate conflict between Western powers and Syrian government allies Russia and Iran.
"We're starting to see a little of the premium come off from geopolitics, and the focus is shifting to inventories," said Bill Baruch, president of Blue Line Futures in Chicago.
Brent has risen 1.4 percent so far this month. It hit a peak last week of $73.09, the highest since late 2014, amid mounting tensions in the Middle East, the possibility of renewed U.S. sanctions against Iran and falling output in Venezuela, where economic crisis has dragged down oil output to multi-year lows.
