Oil prices resumed their upward climb and U.S. futures were lower early Tuesday after Israel’s military issued an evacuation warning to 330,000 people in Iran’s capital Tehran. Asian shares were mixed.

Oil prices fell $1 per barrel on Monday in volatile trading after reports that Iran is seeking an end to hostilities with Israel, raising the possibility of a truce and easing fears of a disruption to crude supplies from the region.

The initial round of Israeli attacks sent oil prices 7 percent higher on Friday. Still, at about $74 a barrel, Brent crude remains below the $80 average for 2024, the Deutsche Bank analysts wrote. The market continued to waver, though, and by Monday, oil prices had fallen about 3 percent.
