Following the US attack on three nuclear sites in Iran, the Home Front Command announced that it has tightened restrictions to the highest level. As part of the changes, it was decided to move all regions of the country from a partial and limited activity rating to a necessary-only activity rating. The guidelines include: a ban on educational activities, gatherings, and workplaces, with the exception of essential businesses.

Before 3 a.m. Israel time, U.S. President Donald Trump announced on his social media account Truth Social early Sunday morning in Israel that the US military had completed its strikes on Fordow, Natanz and Isfahan.

Trump announced on his Truth Social site: "We have completed our very successful attack on the three Nuclear sites in Iran, including Fordow, Natanz, and Isfahan. All planes are now outside of Iran air space. A full payload of BOMBS was dropped on the primary site, Fordow. All planes are safely on their way home. Congratulations to our great American Warriors. There is not another military in the World that could have done this. NOW IS THE TIME FOR PEACE!Thank you for your attention to this matter."

Earlier, explosions were heard in eastern Tehran, the capital of Iran, and in the northern city of Tabriz, according to local reports early Sunday morning. The Iranian news agency Maher reported that air defense systems were activated in these areas.

The U.S. has not yet made a decision on whether to join Israel's campaign against Iran, but it could be made within days, the New York Times reported early Sunday morning. According to two Israeli officials who spoke to the newspaper, they believe Washington is expected to join the fight and is already making preparations for it. According to the talks the officials have had with their U.S. counterparts, an American attack could even take place in the coming days. At the same time, President Donald Trump has returned from his home in New Jersey and is expected to meet with his national security team at the White House soon.

U.S. President Donald Trump posted on his social media network TruthSocial, sharing a Fox News report about the ultimatum the president gave to Iran when he spoke about deciding on an attack "within two weeks." Trump wrote that "only time will tell."

Iran claims to have begun launching drones toward Israel, the AFP news agency shortly after midnight on Saturday night. The country's state television, citing the Revolutionary Guards, claimed that "a large wave of drones has been on its way toward strategic targets across Israel for several hours." Shortly after sirens sounded in the southern Golan warning of UAV infiltration; the drone was intercepted.

The IDF continues to strike at the Iranian UAV array. According to the IDF, on Saturday night the Israeli Air Force began attacking unmanned aerial vehicle (UAV) depots and a weapons depot in southwestern Iran, in the Bandar Abbas area. Meanwhile, Iranian media reported that Iranian air defense systems were activated in Shiraz, Kermanshah and Sanandaj.

Four sources told Reuters that, in the absence of American intervention, Israel is likely to attack the nuclear facility at Fordow alone, and the likelihood of this is increasing every day. Two of the sources noted that the air superiority that Israel has achieved would help in this, but such an operation would still be dangerous. It was also reported that the Israeli position was clarified in a conversation between Prime Minister Benjamin Netanyahu, Defense Minister Israel Katz and IDF Chief of Staff Eyal Zamir with senior U.S. administration officials.

According to the report, Israel feels that there is limited time to carry out the attack due to the high cost of the war, and one source said that “I don’t think they will wait much longer.” Two of the sources said that Israel may try to cause severe damage to the facility rather than destroy it completely.

In another scenario, according to one of the sources, the Air Force would attack Fordow with a series of bunker-busting munitions, similar to the attack in which Hezbollah Secretary-General Hassan Nasrallah was killed, in an attempt to penetrate the underground site. After such an attack, Israel would conduct a raid using special ground forces.

The nuclear reactor in Dimona in southern Israel could be a "legitimate target" for Iran if the war continues to escalate, an Iranian official told Al Jazeera on Saturday evening. He claimed that "our attacks against Israeli targets are very effective, the Israeli military keeps this a secret. We have more advanced missiles than those we have used so far and there is no doubt that we will use them. The Revolutionary Guards have precise information about Israel's stock of interceptor missiles. The forces are planning their attacks to empty its stock of interceptor missiles."

He added that the "U.S. joining Israel's side means that the war will reach regional proportions. Attacking American bases in the region is easier than attacking deep inside Israel."

After the end of Shabbat in Israel, IDF spokesman Brigadier General Effi Defrin issued a statement, announcing that "an Air Force aircraft attacked three Iranian F-14 fighter jets in the heart of the country." He said that the IDF is "damaging all missile production components and preventing the Iranian army from restoring its strategic capabilities."

"At the same time, our forces are deepening the damage to the launch capabilities of the firing systems. The missile launch capabilities they have today are far from the capabilities they had when we embarked on the operation," Defrin said, adding that "in the past week, more than 1,000 drones have been launched toward Israeli territory. In addition to defensive operations, the Air Force is thwarting the chain of command of the drone command."

The IDF spokesperson announced that, following a situational assessment, the Home Front Command's defense policy remains unchanged and in effect until Monday at 8 p.m. Preparations are being made for the possibility that, starting Monday, exceptions may be added for certain areas to allow special education and kindergartens only. This is conditional on the ability to enter a standard protected space within the required time when an alert is sounded.

The New York Times reported that, alongside the deployment of B-2 bombers, additional U.S. fighter jets including F-22, F-16 and F-35 models, were transferred from Europe to bases in the Middle East. These fighter jets could escort the B-2 bombers if they strike Fordow, or defend American bases and forces in the region in case of retaliatory attacks from Iran.

Iran’s air defense systems were activated Saturday in several cities, including Qom, Tehran, Isfahan and Bandar Abbas, state media reported. The Paris-based AFP news agency also documented “loud explosions” in central and northern Tehran.
