From Iran International correspondents - Israel awoke with a slow start on Wednesday morning after Tuesday’s aerial bombardment from Iran as questions loomed over what happens next.

In Tel Aviv, typically busy streets were unusually quiet, with some shops closed and a subdued atmosphere. In Jerusalem, the normally bustling streets of the Old City have been silent all week, as concerns grow over potential attacks during the upcoming Jewish holidays.

Wednesday will mark the first night of the Jewish new year, usually celebrated as a joyful time, but this year, it will be tainted with anxiety. The whole month is marked by a series of religious holidays, with fears they will be marred by further attacks, like last year's Simchat Torah festival.

It comes as Israel prepares for the one-year anniversary of October 7 when Iran-backed Hamas invaded Israel, killing at least 1,100 mostly civilians and taking 251 hostages, 101 of whom remain in captivity.

As the Gaza war persists and more troops are deployed for ground operations in southern Lebanon against Hezbollah, Iran's largest proxy, a second Iranian airstrike since April has heightened tensions across the country.

Prime Minister Benjamin Netanyahu has vowed that Iran “will pay” for the attack which saw almost 200 ballistic missiles overwhelm the country’s aerial defense systems.

Iran has said the attack is over but any retaliation will be met with “vast destruction” as the two countries continue their years-long confrontation. IDF announced on Wednesday that during Iran's overnight attack, strikes were reported at several air bases, but no aircraft were hit.

While during the high holy days, troops would be sent home to spend time with family, the addition of infantry and armored troops from the 36th Division, including the Golani Brigade, the 188th Armored Brigade and 6th Infantry Brigade to south Lebanon, suggests that the operation has moved beyond limited commando raids.

The military has said the ground operation is largely aimed at destroying tunnels and other infrastructure on the border and there were no plans for a wider operation targeting Beirut or major cities in southern Lebanon. It follows the Israeli military's revelation that they had uncovered an Iran-backed Hezbollah plot to imminently repeat last year's October 7 atrocities from Israel's north.

Iran said Tuesday's aerial assault on Israel was solely aimed at military facilities but the Israeli military announced a school in Gedara had been hit, with video footage on social media showing damage to a restaurant in central Tel Aviv. Israel's KAN News reported 100 houses damaged in Hod Hasharon in central Israel. It is not clear if these damages were from direct missile hits or debris falling from intercepted projectiles.

While Iran claims to have hit three military facilities, officially, Israel is saying that most of the barrage was intercepted and the damage seen is shrapnel damage, but it is possible the damage is much wider than believed with footage showing a barrage raining down in the area of Nevatim Air Base.

Ronen Solomon, an intelligence and defense analyst, told Iran International there may a delayed response from Israel due to the religious holiday, even if that may not be the right approach to handling Iran.

“You have to strike immediately to deter them, but Israel may want to delay this and not want to escalate this at the start of the holidays. Yesterday was a traumatic event for people, staying at home in shelters when you’d usually be preparing for the new year, so maybe there is a decision to take some time.”

Another option, he says, is that the US is planning a joint attack, explaining the delay in response. “This could signal something more serious in terms of the response,” he said. “It could be part of the psychological strategy too, or a multi-dimensional attack like we saw in Lebanon, as part of a progressive operation.”

Iran said the assault was a response to Israeli killings of militant leaders including Hezbollah chief Hassan Nasrallah and Hamas political leader Ismail Haniyeh.

Beni Avrahami, whose mother was born in Iran, said the attack had a different feeling to the more common assaults from Gaza. “We are all used to rocket attacks from Gaza now, but when it comes to Iran, it’s different. You don’t really know what’s coming, which changes everything.”

Iranian Foreign Minister Abbas Araghchi said in a post on X early on Wednesday, "Our action is concluded unless the Israeli regime decides to invite further retaliation. In that scenario, our response will be stronger and more powerful."

Tough talk continued from Washington which said it would work with longtime ally Israel to ensure Iran faced "severe consequences" for Tuesday's attack.

“The Israeli people are extremely resilient, but it’s a very worrying situation,” said Ilana Cohen, a resident of Tel Aviv. Speaking on Monday morning, she said, “It’s been a sleepless night, and we pray for quiet.”

The Iranian attack coincided with a terror attack which saw at least seven people killed in a mass shooting in the mixed city of Jaffa which caused chaos as roads closed and police amassed the area amid the Iran attack. Two civilians shot the two terrorists, but it has also stirred up fears of escalation on the ground.

The attackers had infiltrated Israel from Hebron in the West Bank. “It’s all a matter of luck where this could have happened,” said one Tel Aviv resident, Alon Rosenblit. “It can happen anywhere at any time so it makes things very frightening.”

Iran has been funding terror cells in the West Bank since at least last year, according to Israel's defense minister, Yoav Gallant, and now, questions will be asked as to whether the pair were lone wolves, or more of Iran's lackeys.

Although the military insists it is prepared for any scenario, the population remains deeply shaken by the events of October 7, unable to bear the thought of similar incidents overshadowing this year's holy festivals.
