Oil futures jumped as the market reopened Sunday night, building on last week’s surge after Israel attacked Iranian energy facilities over the weekend and underlining fears around potential disruption to Middle Eastern crude flows.

An Israeli strike hit Iran's state broadcaster on Monday while the head of the U.N. nuclear watchdog indicated extensive damage to Iran's biggest uranium enrichment plant and Iran called on the U.S. to force a ceasefire in the aerial war.
