International Benchmark Brent crude traded at $71.36 per barrel at 08.46 GMT while American benchmark West Texas Intermediate (WTI) saw prices of $66.34 per barrel on Monday.
The international Brent crude price saw $67.10 per barrel on Monday, April 9. However, concerns over the Syrian crisis escalated oil prices, which reached as high as $72.72 per barrel on Friday, April 13.
After the limited U.S.-led operations on Bashar al-Assad's regime early Saturday, international Brent oil prices endured limited decreases despite an expected oil price rise.
The U.S., the U.K., and France launched airstrikes on the Assad regime's alleged chemical weapons facilities in Syria on Saturday.
The strikes came after the Assad regime was accused of carrying out a chemical attack in Syria's Douma, which killed 78 civilians and injured hundreds of others.
Furthermore, an increase in the oil rig count in the U.S. helped the oil price decline.
The number of oil rigs in the U.S. increased for the 10th time in the past 12 weeks, according to oilfield services company Baker Hughes data released on Friday.
The oil rig count in the country rose by seven for the week ending April 13, the company said.
