IRAN — SITUATION REPORT

13 July 2026 18:16 ZULU

EXECUTIVE SUMMARY

Tensions between the United States and Iran have escalated significantly following President Trump's declaration of a renewed naval blockade on Iranian shipping and the imposition of a 20% transit fee for vessels in the Strait of Hormuz. Iran has vehemently rejected these measures, asserting its sovereignty over the Strait and issuing warnings against any US intervention, while also launching retaliatory strikes against regional US military assets.

KEY DEVELOPMENTS (past 24 hours)

* US Reinstates Naval Blockade and Transit Toll: President Trump announced the reinstatement of a naval blockade on Iranian ports and a 20% cargo fee for ships transiting the Strait of Hormuz, designating the US as the "Guardian of the Hormuz Strait."

* Iran Condemns US Actions in Strait of Hormuz: Iran's Foreign Minister and the Khatam al-Anbiya Central Headquarters condemned the US blockade and fee, stating Iran will not permit US intervention in the Strait's management. The Persian Gulf Strait Authority (PGSA) reported that passage through the Strait was not possible due to recent US hostile actions.

* US Conducts Strikes on Iranian Targets: US Central Command (CENTCOM) confirmed new waves of strikes against Iranian military targets, including air-defense systems, coastal radar sites, missile and drone capabilities, and small boats. Open-source reporting indicates the first combat use of uncrewed attack boats by the US in strikes on an Iranian naval facility at Bandar Abbas.

* Iran Claims Retaliatory Strikes: Iran's Revolutionary Guards claimed to have launched missile and drone attacks against US military facilities and bases in Bahrain, Kuwait, Oman, and Jordan in response to US strikes.

* Disrupted Strait of Hormuz Traffic: Maritime tracking data indicates only 14 vessels, half commercial and half Iran-flagged, transited the Strait of Hormuz on Sunday, a significant reduction in traffic.

* Iran Rejects IAEA Access: Iran's Foreign Ministry spokesman, Esmail Baghaei, stated that Iran would not agree to the International Atomic Energy Agency's (IAEA) request to access its nuclear facilities, citing US failure to honor commitments under a bilateral memorandum.

* Continued Support for Houthis in Yemen: An Iranian Mahan Air plane successfully landed at Houthi-controlled Sana'a airport despite reported Saudi airstrikes aimed at preventing its arrival. Houthi rebels accused Saudi Arabia of the strikes and vowed retaliation, signaling an end to a period of de-escalation.

* Regional Condemnation of Iran: Qatar's Foreign Ministry condemned Iran's recent attacks on Jordan, Bahrain, and Kuwait.

THREAT ASSESSMENT

The threat level in the Strait of Hormuz and the wider Persian Gulf region is assessed as CRITICAL. Direct military confrontation between US and Iranian forces is ongoing, with both sides conducting strikes and issuing severe warnings. The imposition of a US blockade and transit fee, coupled with Iran's assertion of control, significantly increases the risk of kinetic escalation and disruption to global energy markets. Iran's refusal of IAEA access to nuclear facilities raises proliferation concerns.

DIPLOMATIC STATUS

US-Iran diplomatic relations are severely strained, with President Trump declaring the recent ceasefire and Memorandum of Understanding (MOU) "OVER." Iran has indicated it will not adhere to the MOU if the US fails to meet its commitments. Regional states, including Qatar, have condemned Iranian actions, further isolating Tehran.

OUTLOOK (24–72 hours)

Expect continued high tensions and potential for further military exchanges in the Strait of Hormuz. Iran is likely to maintain its assertive posture regarding the Strait, challenging the US blockade and fee. Further regional destabilization is probable as Iran continues its support for proxy groups and retaliatory strikes. The nuclear issue will remain a flashpoint following Iran's rejection of IAEA inspections.
