TEHRAN (Realist English). On September 5, 2026, explosions of unknown origin were heard near Iran’s Kharg Island — the country’s main oil terminal, through which up to 90% of Iranian crude exports pass.
The incident occurred amid the ongoing US-Iran war, just days after the sides exchanged direct strikes once again.
Iranian media reported explosions, but their source remains unclear: some agencies spoke of sounds from the Persian Gulf with no signs of smoke or fire; others reported a US missile strike on an Iranian tanker. Official Tehran has yet to comment, and the absence of visible damage and conflicting reports leave room for various interpretations.
What Happened Off the Coast of Kharg
On September 5, Iranian semi‑official news agency Fars reported that explosions were heard in the area of Kharg Island. A Fars correspondent on the island said the sounds came from the direction of the Persian Gulf, but no signs of smoke or fire were observed in the waters.
State‑run Nournews reported unconfirmed data from local sources that an Iranian tanker off the coast of Kharg had been struck by a missile launched by US forces.
Agency SNN also reported that “an Iranian tanker was attacked by the United States.” Iranian authorities have not yet made any official statements regarding the incident.
Strategic Importance of Kharg Island
Kharg Island is a key node in Iran’s oil logistics. Up to 90% of Iran’s crude oil exports pass through its terminals, with the bulk destined for China. This small island has long been considered one of the most vulnerable points in Iran’s economy: a strike on it could not only paralyse oil exports but also trigger a harsh military response from Tehran.
The incident comes against the backdrop of recent threats by US President Donald Trump, who had previously spoken of the possibility of striking strategic targets in Iran. Earlier, in March 2026, Trump had already posted a video that, according to him, showed strikes on military facilities on Kharg and warned that the island’s oil infrastructure could be the next target.

What Next: Escalation or Technical Incident?
The reports of explosions off Kharg came just days after the US and Iran exchanged direct strikes again in late August and early September.
If the information about a missile strike on an Iranian tanker is confirmed, this would mark a serious escalation of the conflict: an attack on Iran’s critical export infrastructure could raise the confrontation to a new level.
However, for now, the facts remain unclear. The absence of smoke and visible damage, conflicting reports from Iranian media and official silence from Tehran leave room for various interpretations — from a military attack to a technical incident or even an information provocation.
