Tensions in the Middle East escalate as Israel prepares for a potential military strike against Iran, with U.S. officials predicting an attack could occur before the upcoming presidential election on November 5.

The officials, who spoke on the condition of anonymity to discuss sensitive diplomacy, said that Israel had agreed to focus its next attack on military targets in Iran, instead of those related to Iran’s oil industry or its uranium enrichment efforts. The pledge was first reported by the Washington Post.

The signal is being seen in Washington as a sign of restraint after concerns that an Israeli strike on oil or nuclear facilities could trigger a wider war.
