The U.S. Embassy in Jerusalem early on Sunday lifted its shelter-in-place order for US government employees after the threat from Iranian drones and missiles "diminished."

But the embassy warned that security in Israel "remains complex" and can change quickly.

"The U.S. Embassy in Jerusalem reminds U.S. citizens of the continued need for caution and increased personal security awareness as security incidents often take place without warning," the embassy said in a security alert.

Secretary of State Antony Blinken condemned Iran's attack on Israel, saying the U.S. doesn't seek escalation but will support Israel's right to defend itself and will protect U.S. personnel in the Middle East.

"The United States condemns Iran's attack on Israel in the strongest terms," Blinken said in a statement.

He added that he'll be "consulting with allies and partners in the region and around the world in the hours and days ahead."

The Israel Defense Forces Aerial Defense Array successfully intercepted the majority of Iran's surface-to-surface missile launches using the "Arrow" Aerial Defense System, together with Israel's strategic allies, before the launches crossed into Israeli territory.

A small number of hits were identified, including at an IDF base in southern Israel, where minor damage was caused to infrastructure.

Over the past few hours, many dozens of hostile aircraft, as well as dozens of cruise missiles, from Iran were identified approaching Israeli territory and intercepted. Dozens of IAF fighter jets are currently operating to intercept all aerial threats approaching Israeli territory.

According to a situation analysis by IDF’s Home Front Command, the residents of the following towns: Northern Golan, Nevatim, Dimona, Eilat-City, Be'er Sheva and Arad no longer need to stay near a protected space.

The IDF said it is deployed on all fronts, prepared, and continuing to defend Israeli territory.

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.
