President Joe Biden told reporters he expects an Iranian strike on Israel to occur "sooner than later."

Asked for his message to Iran in this moment, Biden was blunt, saying simply: "Don't."

Asked by ABC News if the U.S. would respond, he said, "We are devoted to the defense of Israel. We will support Israel. We will help defend Israel and Iran will not succeed."

U.S. officials continue to see indicators that Iran could be ready to attack Israel with missile and drone strikes.

Iran has readied a large number of missiles for a possible strike, according to three U.S. officials. Two of the officials said that Iran has readied more than 100 cruise missiles for a possible strike. Iran has also readied a sizeable number of drones that could be used in an attack on Israel, according to one official.

The officials said that Iran has been readying the missiles and drones over the last week.

At least one person is dead and 18 others injured after Israeli settlers allegedly stormed the village of Al-Mughayir in the West Bank, according to the Palestinian Health Ministry.

Some 1,500 settlers burned more than 40 homes and vehicles in the village, according to Marzouq Abu Naim, the deputy mayor of the Al-Mughir Village Council.

The Israel Defense Forces said that "violent riots" erupted in the area while forces searched for a missing 14-year-old boy.

"During the incident, rocks were hurled at IDF soldiers, who responded with fire. Hits were identified," the IDF said in a statement. "Furthermore, IDF and Israel Border Police forces operated to withdraw Israeli civilians who entered the town of Al Mughayyir."

The crowds have since dispersed and there are no longer any Israeli civilians present within the town, the IDF said.

The European Union has sanctioned three terrorist group wings for "widespread sexual and gender-based violence" that occurred in Israel on Oct. 7, the EU Council said.

The sanctioned entities are the Al-Quds Brigades, the armed wing of the Palestinian Islamic Jihad; Nukhba Force, a Hamas special forces unit; and the Qassam Brigades, Hamas' military wing. The Palestinian Islamic Jihad and Hamas are designated as terrorist organizations by the EU.

"Those listed under the sanctions regime are subject to an asset freeze, and the provision of funds or economic resources, directly or indirectly, to them or for their benefit, is prohibited," the EU Council said.

Senate Majority Leader Chuck Schumer said that during a Sunday call between President Joe Biden and congressional leaders there was "consensus" that Congress needs to act quickly to send aid to both Israel and Ukraine.

Schumer said at a news conference in New York that "hopefully" something can be accomplished this coming week to aid both countries.

Earlier Sunday, Biden spoke to Senate Majority Leader Schumer, House Speaker Mike Johnson, House Minority Leader Hakeem Jeffries and Senate Minority Leader Mitch McConnell.

Schumer said the best way to send aid to Israel and Ukraine is for the House to take up and pass the Senate-approved national security supplemental that includes aid to both countries. The Senate passed the $95 billion package in February, but Johnson has not brought it to the floor for a vote.

"The best way to help Israel rebuild its anti-missile and anti-drone capacity is by passing that supplemental immediately. As I said, Israel expended about over a billion dollars in defending itself and the security supplemental would replenish the kind of anti-missile and anti-drone defenses that are in the Arrow, in the David's Sling, and in the Iron Dome," Schumer said.

House Majority Leader Steve Scalise said in a statement Saturday that the House would change its legislative schedule this week to "consider legislation that supports our ally Israel and holds Iran and its terrorist proxies accountable," but it's not yet clear what legislation that will be, or how drastically it might depart from the Senate-passed bill.
