Tensions Escalate: US and Iran Exchange Warnings Amid Strikes Near Key Israeli Locations

Share and Follow

ARAD, Israel — On Sunday, Iran and its ally, the Lebanese militant group Hezbollah, intensified their military engagement with Israel, launching a series of attacks across the nation. This escalation follows recent threats from both the United States and Iran to expand their military objectives in the ongoing Middle Eastern conflict, now entering its fourth week.

Amidst the renewed hostilities, senior Israeli officials visited the southern town of Arad. This location, along with another nearby community, is close to a covert nuclear research facility that was targeted by Iranian missiles late Saturday, resulting in numerous injuries.

During his visit to Arad, Prime Minister Benjamin Netanyahu surveyed the damage and remarked it was a “miracle” that there were no fatalities. He asserted that Israel and the United States are progressing toward achieving their strategic goals in the conflict and called upon the international community for increased support.

In a related development, President Donald Trump issued a stark warning, stating that the United States would target Iran’s power infrastructure if Tehran fails to fully reopen the Strait of Hormuz within a 48-hour timeframe, as announced on Saturday. In response, Iran’s parliamentary speaker cautioned that any U.S. action would lead to Iranian retaliation against American and Israeli energy and infrastructure assets in the region.

The current situation indicates that the conflict, initiated by the U.S. and Israel on February 28, is entering a precarious new phase. This comes despite President Trump’s remarks last week suggesting he might consider scaling back military operations. The conflict has already claimed hundreds of lives, disrupted the global economy, and driven up oil prices.

Hezbollah claimed responsibility for an airstrike Sunday that killed a man in northern Israel while Gulf Arab states – including Saudi Arabia and the United Arab Emirates – said they were intercepting fresh barrages of new Iranian strikes.

Iran responds to Trump threat on its Strait of Hormuz closure

Iran has practically closed the Strait of Hormuz, a chokepoint connecting the Persian Gulf to the rest of the world through which roughly one-fifth of global supply passes. Attacks on ships and threats of further strikes have stopped nearly all tankers from navigating the strait, compelling some of the largest oil producers to make cuts because their crude has nowhere to go.

The blockade is a liability for both the U.S. and its allies in Europe and Asia, who rely heavily on the Persian Gulf supply to meet energy demand and power factories, vehicles and homes. The U.S. lifted some sanctions on Iranian oil at sea to relieve pressure on energy prices.

Trump said if Iran didn’t open the strait, the U.S. would destroy its “various POWER PLANTS, STARTING WITH THE BIGGEST ONE FIRST!”

Iranian parliament speaker Mohammad Bagher Qalibaf responded Sunday on X that if Iran’s power plants and infrastructure are targeted, then vital infrastructure across the region – including energy and desalination facilities – would be considered legitimate targets and “irreversibly destroyed.”

Separately, Iranian officials said they would keep providing safe passage through the strait to vessels from countries other than its enemies.

Nuclear concerns as the war rages

Iran said its strikes in the Negev Desert were in retaliation to an earlier attack on Iran’s main nuclear enrichment site in Natanz, according to state-run media.

Tehran praised the attack as show of strength, even as Israel’s military asserts that Iranian missile launches have gradually decreased in frequency since the war began.

“If the Israeli regime is unable to intercept missiles in the heavily protected Dimona area, it is, operationally, a sign of entering a new phase of the battle,” said Qalibaf, the Iranian parliament speaker.

Dimona is about 20 kilometers (12 miles) west of the nuclear research center, and Arad about 35 kilometers (22 miles) to the north.

Soroka Medical Center, southern Israel’s main hospital, received at least 175 wounded from Arad and Dimona, the hospital’s deputy director Roy Kessous told The Associated Press.

Israel is widely believed to possess nuclear weapons, though it doesn’t confirm or deny their existence. The U.N. nuclear watchdog said on X it had not received reports of damage to the Israeli center or abnormal radiation levels.

Israel denied responsibility for hitting Natanz on Saturday while the Iranian judiciary’s official news agency, Mizan, said there was no leakage. The Pentagon declined to comment on the strike at Natanz, which was also hit in the first week of the ongoing war and in the 12-day war last June.

The U.N. watchdog – the International Atomic Energy Agency – has said the bulk of Iran’s estimated 972 pounds (441 kilograms) of enriched uranium is elsewhere, beneath the rubble at its Isfahan facility.

Iran says strikes also hit hospital

Iran said that, in addition to Natanz, strikes also hit a hospital in Andimeshk. The Health Ministry reported patients and doctors were evacuated to another city.

Iran’s death toll in the war surpassed 1,500 on Saturday, state media reported, citing the ministry. In Israel, 15 people have been killed by Iranian strikes. More than a dozen civilians in the occupied West Bank and Gulf Arab states have been killed in strikes.

The war has also seen noncombat-related accidents, including a U.S. refueling plane crash in Iraq that killed six U.S. service members and a Qatari military helicopter crash on Saturday blamed on a technical malfunction. All seven aboard were killed, Qatari authorities said Sunday.

Hezbollah strike on northern Israel claims first fatality there

The Israeli civilian was killed in the northern town of Misgav Am in what Israel’s military said “seemed to be” a rocket attack. Israeli medics said they found the man in his car and released a video showing two vehicles ablaze.

Hezbollah, an ally of Iran, launched strikes on Israel soon after the war began, saying it was in retaliation for the killing of Iran’s Supreme Leader Ayatollah Ali Khamenei. Israel struck back, bombarding Lebanon and targeting Hezbollah in deadly airstrikes, expanding its presence in southern Lebanon and amassing more troops near the border.

Fighting in southern Lebanese towns have intensified recently as Israel continues its ground operations. Israel on Sunday expanded its list of targets to include all bridges over the Litani River, which Defense Minister Israel Katz said Hezbollah is using to move fighters and weapons into southern Lebanon. It later struck the Qasmiyeh bridge near Tyre.

Katz also ordered the military to accelerate its destruction of Lebanese homes near Israel’s northern border as part of a strategy he described as aligned with Israel’s campaign against Hamas in Gaza.

After Hezbollah fired rockets into Israel on March 2, the Israeli military launched an offensive that Lebanese authorities say killed over 1,000 people and displaced over 1 million. Hezbollah has fired hundreds of rockets into Israel.

Israeli military spokesperson Avichay Adraee issued a warning an hour before the Qasmiyeh bridge near the coastal city of Tyre was struck.

Lebanese authorities say Israel’s strikes have killed more than 1,000 people and displaced more than 1 million.
