Israel is reportedly finalizing plans for a second phase of military strikes targeting Iran’s deeply buried underground missile production and storage facilities, according to multiple intelligence sources cited by leading Israeli and American media outlets on March 6, 2026.

This development comes as the US-Iran War enters its seventh day, with Phase 1 strikes having successfully degraded Iran’s air force and surface-to-air missile systems. Phase 2 would mark a significant escalation, targeting sites that are considerably harder to destroy and would require specialized munitions.

What Are Phase 2 Targets?

Israel’s Phase 2 targets reportedly include:

1. Fordow Uranium Enrichment Facility: Located 90 meters underground near Qom, this facility is Iran’s most protected nuclear-related site and requires specialized “bunker buster” bombs
2. Imam Ali Missile Base: Iran’s largest underground missile complex near Kermanshah, storing ballistic missiles with ranges of 2,000+ km
3. Isfahan Missile Production Facilities: Tunnels and underground workshops where Iran assembles precision-guided ballistic missiles
4. Parchin Military Complex: Allegedly linked to Iran’s nuclear weapons research

US Role in Phase 2

Sources indicate that Israel has requested the United States to provide GBU-57 Massive Ordnance Penetrator (MOP) bombs — the most powerful bunker-buster munitions in existence — for the Phase 2 strikes. The US is reportedly deliberating on whether to supply these specialized weapons.

Global Reactions

The prospect of Phase 2 has triggered alarm across the international community. Russia’s foreign ministry called it “an act of aggression against international law.” China urged immediate de-escalation. The UN Secretary-General called an emergency press conference warning that Phase 2 could “irrevocably destabilize the entire Middle East.”

Iran’s Response

Iranian officials have warned that any strike on underground sites will trigger “the most severe response in Iran’s military history,” without specifying exact measures but hinting at attacks on Gulf oil infrastructure.

Conclusion

Israel’s plans for Phase 2 strikes on Iran’s underground missile sites represent the most dangerous potential escalation in the current US-Iran War. If executed, the strikes could fundamentally reshape the Middle East geopolitical landscape for decades to come.
