Iran-Persian Gulf Tensions Drive Oil Prices to Four-Session High
Oil prices have continued their upward trajectory for the fourth straight session.
Brent crude futures rose $1.57, or 1.6 percent, to $99.49 a barrel as of 00:01 GMT, while US West Texas Intermediate (WTI) crude went up $1.60, or 1.72 percent, to $94.63 a barrel.
The gains came after Iran launched new attacks on US military assets in the Persian Gulf.
Brent crude prices have jumped by a quarter since early August as hopes for a permanent resolution to the six-month-old war faded and fighting flared again.
