WASHINGTON — 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.

The push to encourage Israel to show restraint mirrored ongoing American efforts to curtail Israel’s war against Hamas in Gaza, which is now in its seventh month, and to do more to protect civilian lives in the territory.

While the U.S. and its allies were preparing for days for such an attack, the launches were at the “high end” of what was anticipated, according to the officials, who were not authorized to publicly discuss the matter and spoke on condition of anonymity.

At one point, at least 100 ballistic missiles from Iran were in the air simultaneously with just minutes of flight time to Israel, the officials said. Biden and senior officials monitored the firings and interception attempts in real time in the White House Situation Room. The officials said there was “relief” in the room once they saw that the missile defense efforts had succeeded.

A senior U.S. military official said American aircraft shot down more than 70 drones and cruise missiles, while U.S. destroyers in the eastern Mediterranean Sea downed between four and six ballistic missiles, and an American Patriot missile battery in Iraq shot down one more.

“At my direction, to support the defense of Israel, the U.S. military moved aircraft and ballistic missile defense destroyers to the region over the course of the past week,” Biden said in a statement late Saturday. “Thanks to these deployments and the extraordinary skill of our servicemembers, we helped Israel take down nearly all of the incoming drones and missiles.”

Administration officials said the call demonstrated that despite differences over the war in Gaza, the U.S. commitment to Israel’s defense was “ironclad” and that the U.S. would mount a similar effort again if needed.

Biden had a call Sunday with Jordan’s King Abdullah II in which the king said any “escalatory measures” by Israel would lead to a broader conflict in the region, according to the Royal Court. The White House said the situation in Gaza was discussed, and the leaders reaffirmed their cooperation “to find a path to end the crisis as soon as possible.”

After the G7 videoconference Sunday, the group of advanced democracies — the U.S., Italy, Japan, Germany, France, Britain and Canada issued a joint statement, “unequivocally condemning in the strongest terms” the direct attack by Iran while expressing “our full solidarity and support to Israel” and reaffirming “our commitment towards its security.”
