Lead
On Thursday evening, Israeli forces carried out fresh airstrikes on central Beirut and parts of Tehran, producing large smoke plumes near Lebanon’s government district and activating air defenses across Iran’s capital. The strikes followed a defiant public statement by Iran’s newly installed supreme leader, Mojtaba Khamenei, who said the blockade of the Strait of Hormuz must continue and vowed to avenge the dead. Israeli Prime Minister Benjamin Netanyahu, speaking the same night, said he was creating conditions that could weaken Iran’s regime but stopped short of predicting its collapse. The attacks deepen fears that the Israel–Hezbollah front and the wider U.S.–Israeli campaign against Iran are widening into major regional combat.
Key Takeaways
- Israel launched a new wave of strikes on central Beirut and Tehran on March 12, hitting areas a few hundred meters from Lebanon’s government headquarters and triggering Tehran’s air defenses.

- Iran’s new supreme leader, Mojtaba Khamenei, ordered continued use of the Strait of Hormuz as leverage and vowed reprisals; his remarks were his first public statement since succeeding his father.
- Oil markets reacted: Brent crude briefly topped $100 a barrel, with analysts and S&P Global Energy estimating global oil flow reductions as large as 17 million barrels a day from the Persian Gulf region.
- Up to 3.2 million people are preliminarily assessed as displaced inside Iran, according to U.N. agency estimates; Lebanon’s child displacement figures include roughly 200,000 children uprooted, War Child reported.
- Russia airlifted more than 13 metric tons of medical supplies to Iran via Azerbaijan on orders from President Vladimir Putin, according to the Russian emergency ministry.
- U.S. Central Command posted figures claiming roughly 6,000 targets in Iran were struck and that more than 90 vessels were destroyed since operations began on Feb. 28; those numbers have not been independently verified.
Background
The war began on Feb. 28 with coordinated U.S. and Israeli strikes on Iran; Iranian retaliation has included missile and drone strikes across the Gulf and attacks on commercial shipping. Tehran’s leadership change after the death of Ayatollah Ali Khamenei — killed in early strikes — placed Mojtaba Khamenei at the center of command at a moment of intense military escalation. The conflict quickly drew in state and nonstate actors: Hezbollah in Lebanon has launched rockets into northern and central Israel, while Iran-backed militias and some Iraqi factions have struck bases tied to U.S. interests.
Economic and civilian effects escalated alongside the fighting. Iran and Gulf sea lanes are vital for global oil and gas: historically about 20 million barrels a day transited the Strait of Hormuz. Disruptions from attacks on tankers, port closures in Iraq and Oman, and threats to shipping have pushed benchmark oil prices sharply higher and prompted the IEA and G7 countries to coordinate releases from strategic reserves. Humanitarian organizations and national authorities report extensive displacement, damaged infrastructure and growing shortages of medicine and fuel.
Main Event
On the evening of March 12, Israeli aircraft and, according to local accounts, strikes of varying types hit central Beirut neighborhoods including Bachoura and the seaside Ramlet al-Baida, as well as targets in Tehran. Videos and witness testimony showed thick plumes of smoke rising near Beirut’s government center and sand-strewn, bloodied corniche sidewalks where displaced families had been sheltering. Lebanese officials said at least eight people were killed in one seaside strike and dozens more wounded.
In Tehran, state and semiofficial outlets reported air-defense activations after what Iran described as a large-scale Israeli strike on several sites. Iranian officials, citing domestic assessments and a U.N. statement, put the civilian death toll in their country at more than 1,348. Israeli statements said they were targeting Iranian and allied militia infrastructure; Iran said its facilities and some civilian areas were struck, intensifying public alarm.
Prime Minister Benjamin Netanyahu addressed reporters Thursday night and tempered earlier calls for Iranians to rise up, saying he could not be certain the Iranian people would topple the regime but asserting that Iran would be weakened even if it endured. Meanwhile, Lebanon’s prime minister, Nawaf Salam, appealed on television for Lebanon not to become “an open arena for the wars of others,” as strikes encroached on parts of Beirut long considered comparatively safe.
At sea, two tankers were attacked off Iraq’s coast earlier in the day; Iran’s Islamic Revolutionary Guard Corps claimed one incident. Iraq and Oman temporarily closed oil terminals, and U.S. officials said the Navy could begin escorting commercial vessels through the Strait of Hormuz by month’s end. Markets reacted immediately: Brent briefly rose above $100 a barrel before retreating to around $97 by late trading.
Analysis & Implications
The expansion of strikes into central Beirut signals a tactical shift with strategic consequences. Israel’s stated objective to dismantle Hezbollah capabilities has led operations into densely populated urban areas, increasing civilian harm and displacement and complicating any effort to limit the war geographically. Lebanon’s internal politics — a government formed only last year and a fragile security apparatus — offer limited capacity to control or disarm powerful nonstate actors such as Hezbollah.
Iran’s emphasis on keeping the Strait of Hormuz closed is both military and economic pressure: by threatening a choke point that once funneled roughly a fifth of global oil supply, Tehran seeks to impose costs on its adversaries and on global consumers. Analysts warn that even partial, prolonged closures would push oil prices to new records and amplify inflationary pressures globally, especially for diesel and jet fuel which have fewer alternate supplies.
Third-party states are under immediate pressure to choose sides or to try to de-escalate. India, heavily dependent on Iranian and Russian oil, faces diplomatic and commercial dilemmas after recent high-level visits to Israel and pressure from the United States. Gulf states, NATO members and regional actors must balance economic exposure to energy shocks against security partnerships and public opinion that may tilt toward Iran in parts of the region.
Cyber and asymmetric fronts are likely to persist and expand. The reported hack of medical-equipment maker Stryker — claimed by a group calling itself Handala and framed as retaliation for strikes on an Iranian school — underscores the risk that nonstate cyber actors will target firms with perceived links to adversaries, spreading disruption beyond military domains into global commercial and health infrastructure.
Comparison & Data
| Metric | Reported Figure |
|---|---|
| Civilian deaths in Iran (government figure) | 1,348+ |
| Deaths in Lebanon (official) | 680+ |
| Displaced in Lebanon (official) | 800,000+ |
| Displaced inside Iran (UNHCR preliminary) | 3.2 million |
| Children displaced in Lebanon (War Child) | ~200,000 |
| Estimated Gulf oil flow reduction (S&P Global) | ~17 million bpd |
The table brings together figures cited by national authorities, humanitarian agencies and energy analysts. Numbers vary by source and are updated as field verification continues; displacement totals reflect preliminary assessments and may change as borders, shelters and reporting conditions evolve. Energy analysts emphasize that the cited daily flow reductions are extraordinary compared with past disruptions and would require large-scale mitigation to prevent sustained price shocks.
Reactions & Quotes
Lebanese and international leaders reacted publicly as strikes reached new parts of Beirut and Tehran.
“We cannot, under any circumstances, accept that Lebanon once again becomes an open arena for the wars of others.”
Prime Minister Nawaf Salam (Lebanon)
Salam’s televised statement framed the Beirut strikes as a national affront and signaled his government’s intent to seek agreements that might limit spillover, even as domestic capacity to control militias remains constrained.
“The lever of closing the Strait of Hormuz must continue to be used.”
Mojtaba Khamenei (Supreme Leader of Iran)
Khamenei’s brief public declaration laid out the strategic aim to deny adversaries normal passage in a critical waterway, a threat with direct economic consequences for global oil markets and for countries dependent on Gulf supplies.
“We’ve seen reports of civilian commercial ships attacked — this is a major escalation.”
John Healey (U.K. Secretary of State for Defence)
British authorities warned about mine-laying and maritime risks and signaled deployment of autonomous mine-countermeasure systems alongside allies, reflecting rising concern among NATO partners over freedom of navigation and commercial safety.
Explainer / Glossary
Unconfirmed
- The U.S. Central Command’s posted tally of ~6,000 targets struck in Iran and the claimed destruction of over 90 vessels has not been independently verified by third-party sources.
- Reports that Mojtaba Khamenei was physically injured on Feb. 28 are cited by some Iranian officials but lack on-the-record confirmation and visual evidence.
- Attributions of specific tanker attacks to particular militias or states remain disputed in several cases and are under investigation by regional authorities.
Bottom Line
The strikes on central Beirut and Tehran and Iran’s explicit vow to keep the Strait of Hormuz closed illustrate a dangerous widening of this conflict from a principally state-on-state campaign into multi-front warfare that blends air, maritime, militia and cyber operations. The humanitarian toll is already severe, with thousands reported dead and millions displaced across several countries, and civilian infrastructure — ports, hospitals, universities — repeatedly struck.
Energy markets and global supply chains are acutely vulnerable: even temporary interruptions to Hormuz transit or Gulf exports push prices higher and strain fuel-dependent sectors worldwide. Diplomatic pressure and the unprecedented strategic release of oil reserves by major economies have so far blunted, not eliminated, market volatility. The coming days will be decisive: efforts to protect commercial shipping, limit urban bombardment and secure humanitarian corridors will determine whether the war remains regionally contained or escalates further.
