The U.S. military has moved a large number of refueling aircraft to Europe to provide options to President Donald Trump as Middle East tensions erupt into conflict between Iran and Israel, two U.S. officials told Reuters on Monday,

Israel and Iran have begun a new round of attacks, as the conflict between the two heavily armed rivals enters its fourth day.

As the Iran-Israel conflict intensifies, the U.S. deploys the USS Nimitz aircraft carrier along with support tankers to bolster military readiness.

The USS Nimitz strike group is deploying to the Middle East amid ongoing strikes between Israel and Iran that threaten to develop into a broader conflict, a U.S. defense official confirmed Monday.

British Prime Minister Keir Starmer said all G7 leaders agree they “have to find a way to de-escalate the situation” in the Middle East because the Israel-Iran conflict risks inflaming the “tinderbox” of Gaza and hurting the global economy.

Trump does not intend to sign the document in Canada alongside his Canadian and European counterparts at the G7 summit in Alberta.

The confrontation with Tehran has forced a shift in the U.S. plan for a diplomatic deal in Iran and efforts to disentangle from 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.

Global energy executives gathered in the Malaysian capital on Monday for an industry conference with an eye on the dramatic escalation in the conflict between Israel and Iran, which has fuelled worries that it could widen and disrupt supply.
