Middle East SITREP: US-Iran War Day 13 — Gulf Closure and Multi-Front Escalation, March 12, 2026

The US-Iran conflict, now in its second week since initiation on 28 February 2026, has escalated into a multi-domain war involving airstrikes, missile barrages, naval disruptions, and cyber operations. US and Israeli forces have conducted extensive strikes on Iranian military infrastructure, including airfields, missile sites, and IRGC checkpoints, resulting in significant casualties and displacement of up to 3.2 million Iranians. Iran, under new Supreme Leader Mojtaba Khamenei, has retaliated with IRGC missile and drone attacks on US bases, Israeli positions, and commercial shipping in the Persian Gulf, effectively closing the Strait of Hormuz and causing global oil price surges. Hezbollah's involvement has intensified cross-border exchanges with Israel, while proxy actions in Iraq and Syria add to regional instability. Humanitarian impacts are severe, with over 2,000 deaths reported, including civilians and US personnel, alongside damage to cultural sites and widespread evacuations in Lebanon and Iran. International responses include UN condemnations, Russian humanitarian aid, and calls for de-escalation from Oman and Russia. US intelligence assesses the Iranian regime as stable, with no imminent collapse, though internal military strains like desertions and supply shortages are evident. Economic fallout includes $11 billion in US expenditures in the first week and cyber retaliations targeting US firms. Allied support from Russia and China bolsters Iran's electronic warfare capabilities, eroding US-Israeli dominance. The conflict risks broader involvement of Gulf states, with incidents in Dubai, Kuwait, and Basra highlighting spillover effects.
