Oil prices risk rocketing further should crude supplies become disrupted from a widening Middle East conflict after Israel struck military and nuclear facilities in Iran, analysts said Friday.

Tensions escalate as Iran launches a missile barrage on Israel, retaliating for Israeli strikes on Iranian nuclear sites and the killing of military commanders. Explosions rocked Jerusalem and Tel Aviv, with many missiles intercepted. Iran’s Revolutionary Guard claimed responsibility, targeting Israeli military positions. The US had cautioned against strikes that could derail nuclear negotiations.

The U.S. military has helped shoot down Iranian missiles that were headed toward Israel, two U.S. officials said on Friday.
