**No, it's not true.**
This recycles old footage from the March 2026 US-Israeli strikes on Tehran-area oil depots and facilities (e.g., Shahran, Shahr-e Rey). No credible reports confirm any new massive joint attack destroying a major oil refinery in Tehran today. Recent US strikes (early July) targeted sites like Kharg Island amid renewed tensions, not this.
If it *had* happened, expect sharp global oil price spikes, billions in rebuilding costs, heavy local pollution/health damage from fires in populated Tehran, and major escalation risks.
