DUBAI – Explosions sent plumes of dark smoke over western Tehran before dawn on March 7, 2026, as Israel said it had launched a broad wave of strikes and Iran fired missiles at Israel. Sirens and loud booms were heard in Jerusalem, driving residents to bomb shelters, while the United States warned a new phase of attacks would be the most intense of the weeklong war.
The overnight exchange widened a conflict already rippling across the Middle East, drawing in U.S. forces and heightening fears of a direct regional confrontation. U.S. officials approved fresh military support for Israel and signaled further operations, while Iranian officials vowed to defend the country and threatened retaliation across multiple fronts. There were no immediate reports of casualties from Israel’s emergency services.
Cross-border strikes and alerts on March 7, 2026
The latest barrage underscored how battle lines now extend from Iran’s capital to the eastern Mediterranean and the Gulf.
- Tehran: Explosions flashed and smoke rose over the city as Israel said it began a “broad wave of strikes” on what it described as military and command targets.
- Israel: Loud booms sounded in Jerusalem; incoming Iranian missiles triggered nationwide alerts and sent people to shelters, officials said.
- Bahrain: Air-raid sirens sounded as Iranian attacks targeted the island kingdom, which hosts the U.S. Navy’s Fifth Fleet and is a key node in American maritime operations.
- Saudi Arabia: Authorities said drones headed toward the Shaybah oil field were destroyed and a ballistic missile launched toward Prince Sultan Air Base – which hosts U.S. forces – was shot down, highlighting the vulnerability of regional energy and defense infrastructure.
Washington backs Israel and signals heavier strikes
U.S. officials approved a new $151 million arms sale to Israel, adding precision-guided munitions and air defense components to earlier emergency transfers under existing U.S. foreign military sales authorities. The move underscored Washington’s decision to double down on military backing even as civilian casualties rise across the region.
President Donald Trump said he would not negotiate with Iran without its “unconditional surrender,” and Iran’s U.N. ambassador said the country would “take all necessary measures” to defend itself, framing the confrontation in terms that leave little room for immediate diplomacy.
U.S. Treasury Secretary Scott Bessent said in a television interview that the “biggest bombing campaign” of the war was still to come, signaling to markets and U.S. allies that Washington expects a further escalation rather than a quick cease-fire.
“There will be no deal with Iran except UNCONDITIONAL SURRENDER!” After a surrender, “and the selection of a GREAT & ACCEPTABLE Leader(s),” he wrote, the U.S. and its allies will help rebuild Iran, making it “economically bigger, better, and stronger than ever before.”
The remarks, posted on social media and amplified by conservative media outlets, amounted to an explicit call for regime change and a break from recent U.S. statements that had focused on deterrence and containment.
Iran’s U.N. ambassador, Amir Saeid Iravani, condemned the statement and said Iran “does not accept and will never allow any foreign power to interfere in its internal affairs,” calling Trump’s comments a violation of the U.N. Charter’s principles on state sovereignty.
U.S. and Israeli strikes inside Iran, and shifting war aims
Officials said the United States and Israel have hit targets tied to Iran’s military, leadership, and nuclear program over the past week, including Revolutionary Guard facilities, command centers, and air defense sites. Publicly stated goals and timelines have shifted, with U.S. messaging at times suggesting an effort to topple Iran’s government or elevate new leadership from within, and at other moments emphasizing the narrower objective of degrading Iran’s ability to strike U.S. and allied forces.
Diplomats in Washington and European capitals said the lack of a clearly articulated endgame is complicating efforts to build a broader coalition response and to use existing mechanisms – including U.N. Security Council resolutions on Iran’s nuclear activities – to press for de‑escalation.
U.S. intelligence flags Russian assistance to Iran
Two officials familiar with U.S. intelligence said Russia has provided Iran with information that could help Tehran strike American warships, aircraft, and other regional assets, including targeting data and assessments of U.S. force posture. They cautioned there is no indication Moscow is directing how the information is used, but said the assistance has factored into U.S. military planning and threat assessments.
The Kremlin said Russian President Vladimir Putin spoke by phone on March 6, 2026, with Iranian President Masoud Pezeshkian and offered condolences over the killing of Iranian Supreme Leader Ayatollah Ali Khamenei. Russian officials publicly called for restraint while privately stressing to Iranian counterparts that they oppose any attack that could trigger direct NATO involvement, according to one of the officials.
Deadly school blast in Minab; U.S. role under review
New information surfaced indicating that a February 28, 2026, explosion at a school in Minab – about 1,100 kilometers (680 miles) southeast of Tehran – was likely caused by U.S. airstrikes that also hit an adjacent Revolutionary Guard-associated compound. The material cited included satellite imagery, expert analyses, a U.S. official, and public disclosures by U.S. and Israeli militaries.
Iranian state media said more than 165 people were killed, most of them children, and broadcast images of collapsed classrooms and grieving families. Iran has blamed Israel and the United States; neither country has accepted responsibility, and U.S. Defense Secretary Pete Hegseth said the United States is investigating whether its munitions or targeting data contributed to the blast.
Human rights lawyers said that if U.S. involvement is confirmed, the Minab strike could raise fresh questions under international humanitarian law about the proportionality and distinction of the attack, potentially exposing commanders to scrutiny by international bodies and domestic courts.
Lebanon front flares; airstrikes on Beirut suburbs
Hezbollah said its fighters clashed late March 6, 2026, with an Israeli force that landed in mountains of eastern Lebanon. The Lebanese Health Ministry reported at least three people killed. Israel did not acknowledge the fighting and did not immediately respond to requests for comment.
Israel has conducted waves of airstrikes on Beirut’s southern suburbs, where Hezbollah maintains a large presence alongside hundreds of thousands of civilians. The densely populated districts, long considered Hezbollah’s political and logistical heartland, have increasingly become a central battleground.
The Lebanese Health Ministry said at least 217 people have been killed and 798 wounded since Monday, March 2, 2026. Roads were jammed with evacuees, smoke rose over southern districts, and two hospitals evacuated patients and staff, adding pressure to a health system already weakened by years of economic crisis.
“What can we do? We prayed here under the tree. During the night, we slept in the car because there is no place to stay,” said Jihan Shehadeh, among the tens of thousands displaced to schools, public parks, and informal shelters.
Casualties mount across the region
Officials in affected countries reported rapidly rising death tolls as strikes intensified on multiple fronts:
- Iran: At least 1,230 people killed, including security personnel and civilians, according to Iranian authorities.
- Lebanon: More than 200 people killed since March 2, 2026, as Israeli airstrikes expand beyond border areas into Beirut’s southern suburbs.
- Israel: Around a dozen people killed in missile and drone attacks and in cross‑border fire from Hezbollah.
- United States: Six U.S. troops killed in incidents linked to the conflict, including attacks on bases hosting American forces.
Aid groups warned that displacement, power cuts, and damage to water systems in Lebanon and parts of Iran could drive the civilian toll higher even if front-line fighting slows, and urged all parties to respect the laws of war.
Energy shock concerns grow as oil tops $90
Benchmark U.S. crude rose above $90 per barrel on March 6, 2026, for the first time in more than two years, as traders priced in the risk of a prolonged disruption to Gulf exports and potential attacks on energy infrastructure.
Qatar’s energy minister, Saad al-Kaabi, warned the conflict could “bring down the economies of the world,” predicting a shutdown of Gulf energy exports that could push oil to $150 a barrel. Finance ministries in Europe and Asia have begun contingency planning for fuel subsidies and emergency stock releases, fearing a renewed inflation shock that could complicate monetary policy and strain public budgets.
The International Energy Agency has not yet announced coordinated stock draws, but officials said member states are reviewing legal authorities and strategic reserves in case shipping lanes such as the Strait of Hormuz are threatened.
Leadership succession moves inside Iran
Iranian state television reported on March 6, 2026, that a leadership council had begun discussing how to convene the country’s Assembly of Experts, which selects the supreme leader. The body is empowered under Iran’s constitution to choose and, in theory, dismiss the supreme leader, making it the central institutional arena for the country’s political succession.
Trump has said he should be involved in choosing a replacement for Khamenei and called Mojtaba Khamenei “a lightweight,” a remark that Iranian officials denounced as “colonial” and “illegitimate.” Iravani rejected any foreign role in Iran’s internal affairs and said decisions about succession would be made “solely within the framework of Iran’s constitution and the will of its people.”
- Assembly of Experts: An elected clerical body constitutionally empowered to choose and, if necessary, dismiss Iran’s supreme leader. Its procedures and authority are set out in Iran’s constitution, which functions as the country’s primary governing framework for leadership succession.
The crisis has also sharpened attention on broader international rules governing the use of force and collective security. Diplomats noted that both Iran and Israel are operating in a region where the U.N. Charter’s prohibition on the threat or use of force and its provisions on self‑defense and Security Council authority remain the formal legal backdrop to decisions now being taken in war rooms from Tehran to Washington.
As of March 7, 2026, Iranian state television said the leadership council was discussing convening the Assembly of Experts to select the new supreme leader, a choice that will shape Iran’s posture toward the United States, Israel, and the wider region long after the current round of fighting ends.
