Brent crude rose 4.41 percent to $87.80 a barrel and WTI crude rose 4.23 percent to $82.61 a barrel on Wednesday, rebounding from a nearly 5 percent decline the prior session. Reports indicate Saudi Arabia joined US CENTCOM in air strikes on Iran-backed militant targets in Iraq following drone attacks on Saudi oil facilities, though Saudi officials stated the kingdom was not seeking escalation. Attribution of the price increase to supply concerns from an Iranian missile attack is disputed between sources.
