Brent crude oil prices fell below $66, or by 1.36 percent, per barrel on Tuesday due to the high supply figures from Middle Eastern producers and a stronger U.S. dollar.
The crude prices had peaked on Monday due to the clashes in Yemen and Iraq, which raised fears on disruption of oil transfers, up to $67.7 per barrel.
Brent crude was traded at $65.37 at 12:45 pm GMT.
The data from Joint Organizations Data Initiative shows that Saudi Arabia exported the highest crude in almost a decade, reaching to 7.9 million barrels per day in March, pushing prices further down.
OPEC's April output rose to 30.84 million barrels per day, mb/d, from 30.82 mb/d in March by 18,000 barrels, according to the organization's latest report.
The Iraqi forces lost the capital of Anbar province, Ramadi, to Daesh militants on Sunday, while the Saudi-led airstrikes restarted to hit Yemen's Houthis after a 5-day humanitarian ceasefire.
U.S dollar bounced back from four months low and edged up against a basket of major currencies on Tuesday, which makes oil more costly for countries using other currencies.
