WASHINGTON (AP) — The United States on Sunday highlighted its role in helping Israel thwart Iran’s aerial attack as President Joe Biden convened leaders of the Group of Seven countries in an effort to prevent a wider regional escalation and coordinate a global rebuke of Tehran.

The U.S. assisted Israel in shooting down dozens of drones and missiles fired by Iran on Saturday in what was the first time it had launched a direct military assault on Israel. Israeli authorities said 99% of the inbound weapons were shot down without causing any significant damage.

U.S. officials said that despite the high interception rate, Iran’s intent was to “destroy and cause casualties” and that if successful, the strikes would have caused an “uncontrollable” escalation across the Mideast. U.S. officials said Biden told Israeli Prime Minister Benjamin Netanyahu, in an effort to contain tensions, that Washington would not participate in any offensive action against Iran, and the president made “very clear” to Netanyahu “that we do have to think carefully and strategically” about risks of escalation.
