World War 3: U.S. and Israel Launch Major Military Strikes on Iran

In a dramatic escalation of Middle East tensions, the United States and Israel launched a major coordinated military offensive against Iran on 28 February 2026, marking one of the most serious confrontations involving these powers in decades. Multiple international media outlets report widespread strikes and sustained responses from Tehran, raising global concern.

What Happened

On the morning of 28 February, Israel announced it had begun a pre‑emptive military attack on Iran in coordination with U.S. forces. Israel’s defence ministry described the operation as aimed at countering what it called a “existential threat” from the Iranian government, particularly regarding Iran’s nuclear programme and regional military capabilities.

Shortly afterward, President Donald Trump confirmed that U.S. military forces had begun “wide‑ranging combat operations” on Iranian targets, stressing that the aim was to neutralise threats posed by Tehran to U.S. interests and key regional allies.

The assault reportedly involved hundreds of targets across western and central Iran, including air defence systems, missile sites, and other strategic military infrastructure. Explosions were heard in Tehran and several other Iranian cities, and Iran’s airspace was closed in response.

Iran’s Retaliation

Iran responded swiftly with multiple waves of missile launches and drone strikes directed at Israeli territory and U.S. military assets in the region. The Iranian armed forces described their counter‑offensive as part of an operation dubbed Al‑Wa‘d al‑Sadiq 4 (The True Promise 4).

Israeli defence officials reported that some Iranian missiles and drones were intercepted by Israel’s air defenses, with debris causing limited material damage but no immediate reports of civilian casualties.

Human and Military Impact

According to the Iranian Red Crescent, the strikes on Iranian soil resulted in significant casualties, with over 200 people reported killed due to the attacks — a figure that is expected to rise as assessments continue. Iran has closed its airspace and halted all civilian flights until further notice.

Both sides have sustained ongoing exchanges, and the regional atmosphere remains highly volatile, with fears that the fighting could broaden into a wider conflict.

Global Reactions

World leaders are responding with alarm and caution:

• Russia strongly condemned the U.S.–Israel military action, calling it an “unprovoked act of aggression” and urging a return to diplomacy while emphasising the risk of destabilising the Middle East further.

• Several countries have expressed concern over the rapid escalation and called for restraint, highlighting the need for adherence to international law and urgent diplomatic efforts to prevent wider fallout.

International organisations, including Human Rights Watch, urged all parties to respect the laws of war and protect civilian lives amid ongoing hostilities.

Why This Matters

Analysts say this offensive could be one of the most consequential Middle East confrontations since the 1991 Gulf War:

• It involves direct engagement between major militaries and high‑level strategic targets.

• It carries the risk of drawing in allied groups and regional proxies, potentially expanding fighting beyond Iran’s borders.

• It could have dramatic consequences for global oil markets, international diplomacy, and the security of countries far from the conflict zone.

While some observers describe the crisis as a regional war, others caution that it is not yet a “World War III”, but it certainly represents one of the most serious escalations in decades, with global eyes on how it unfolds in the coming days and weeks.

What to Watch Next

• Whether Iran continues its retaliatory strikes or escalates further.

• How regional powers — including Gulf states, Turkey, and Russia — navigate their responses.

• Whether diplomatic channels can be re‑opened to prevent the conflict from widening.
