The armed attack on the headquarters of Libya's National Oil Corporation on Monday caused oil prices to rise, the Wall Street Journal reported.
The newspaper added that the attack, along with concern about the production of Iran and Iraq, contributed to the rise in prices, with Brent crude price of 77.67 dollars per barrel, up 1.09%.
West Texas crude was up $ 68.35 a barrel, or 0.87 percent, according to the US newspaper.
An armed group attacked the headquarters of the National Oil Corporation (NOC), located in the heart of Tripoli this morning. While no one has claimed responsibility yet, the Interior Ministry in the Government of National Accord blamed ISIS for the attack.
"The attack on the Oil Corporation is a reminder that there are serious geopolitical problems that risk supply in several places in the world" said Helima Croft, an analyst at Royal Bank of Scotland Capital Markets.
