President Joe Biden swept into wartime Israel for a 7 1/2-hour visit Wednesday that produced a heaping dose of vocal support, a deal to get limited humanitarian aid into Gaza from Egypt, likely by the end of the week, and a plea for Israelis not to allow rage over the deadly Hamas attack to consume them, according to AP.

“I understand. Many Americans understand,” Biden said as he wrapped up his stay in Tel Aviv, likening the Oct. 7 Hamas assault to the attacks against the United States on Sept. 11, 2001, that killed nearly 3,000 people. “You can’t look at what has happened here ... and not scream out for justice,” he said.

“But I caution this: While you feel that rage, don’t be consumed by it,” he said. “After 9/11, we were enraged in the United States. And while we sought justice and got justice, we also made mistakes.”

Biden urged Israel to step back from the brink, not just to ease growing tensions in the Mideast that threaten to spiral into a broader regional conflict, but also to reassure a world rattled by images of carnage and suffering, in Israel and Gaza alike. One million people have been displaced in roughly 10 days, according to the United Nations.

Officials in Gaza quickly blamed an Israeli airstrike. Israel denied it was involved and released a flurry of video, audio and other information that it said showed the blast was instead due to a missile misfire by Islamic Jihad, another militant group operating in Gaza. The Islamic Jihad dismissed that claim. The Associated Press has not independently verified any of the claims or evidence released by the parties.

Biden said data from his Defense Department showed that the explosion was not likely caused by an airstrike by the Israeli military. A White House National Security Council spokesperson followed up later with a post on social media that an analysis of “overhead imagery, intercepts and open source information” showed Israel was not behind the attack. But the U.S. continues to collect evidence.

“Based on what I’ve seen, it appears as though it was done by the other team, not you,” Biden told Netanyahu.

The leaders of the U.S. Senate Intelligence Committee in a joint statement said they felt confident the explosion was “the result of a failed rocket launch” by militants and not an Israeli airstrike.
