Israel-Gaza updates: 22, including 18 children, reported dead in Rafah strikes

Israeli military officials have submitted "a wide range of options" to respond to Iran’s missile strike Saturday, Israeli Defense Federation (IDF) spokesperson Peter Lerner told reporters early Monday morning in Tel Aviv.

The IDF’s response could be "strike or no strike," according to Lerner, who noted, there are "a lot of different scenarios in between those two."

The Israeli government will "decide on the steps forward" as early as Monday or within the coming days, Lerner said.

When asked about Iran’s "substantial" missile strike being intercepted with minimal damage, Lerner said, "Just because we were successful in intercepting, we shouldn't underestimate what Iran did."

"We can't take that lightly," Lerner said.

The Israeli Defense Force (IDF) has eased homefront command guidelines after closing schools and limiting gatherings ahead of Iran’s missile strike Saturday.

"It was decided to restore educational activities across Israel," the IDF said in a statement early Monday, local time. The changes went into effect at midnight, according to Israel's Home Front Command.

Communities near the northern border and the Gaza Strip can also resume educational activities "in subject with restrictions."

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.

At least nine Iranian missiles that breached Israel's air defenses struck two of Israel's air bases, but no significant damage was reported, a senior U.S. official told ABC News.

Five ballistic missiles hit the Nevatim Air Base, damaging a C-130 transport aircraft, an unused runway and empty storage facilities, the official said. Four additional ballistic missiles hit the Negev Air Base, but there were no reports of significant damage, the official said.

A spokesperson for the Israel Defense Forces said earlier Sunday that 99% of the 300 "threats of various types" Iran launched at Israel, including 120 ballistic missiles and more than 30 cruise missiles, were intercepted by Israel's air defense system and Israeli Air Force fighter jets, as well as "aerial defense systems and aircraft of our partners."
