The Middle East was plunged into a new, volatile conflict following a massive joint military operation launched by the United States and Israel against Iran on Saturday. Codenamed "Operation Epic Fury" by the US, the strikes targeted key Iranian leadership and military installations, culminating in the confirmed death of Iran's Supreme Leader, Ayatollah Ali Khamenei. This audacious plan, aimed at decapitating the Iranian regime, was initiated after intelligence suggested an opportunity to simultaneously target the country’s leaders and mullahs during their gatherings. Israeli intelligence had been tracking Khamenei's movements, identifying a window for these attacks.

US President Donald Trump announced the commencement of "major combat operations" in a video statement, stating that the goal was regime change and to prevent Iran from acquiring nuclear weapons. He declared that Iran "will never have a nuclear weapon" and warned that US troops might incur casualties, a reality "that often happens in war." The US administration cited Iran’s arsenal of conventional missiles as an "intolerable threat" that Tehran consistently refused to address. Additionally, suspicions about Iran's nuclear enrichment being for peaceful purposes and intelligence indicating Iran was rebuilding sites destroyed in the previous "Operation Midnight Hammer" contributed to the decision to strike. Trump's special envoys, Steve Witkoff and Jared Kushner, had also ended talks in Geneva disappointed, concluding Iran was stalling on demands to destroy nuclear enrichment sites and deliver uranium stockpiles.

Ayatollah Ali Khamenei, who died at the age of 86, had ruled Iran as Supreme Leader since 1989, presiding over a complex theocratic system enforced brutally at home. His rule saw Iran become one of the world's biggest state sponsors of terrorism, leading the "axis of resistance" comprising groups like Hezbollah, Hamas, and Houthi rebels. Domestically, Khamenei's era was marked by severe repression, including mass protests such as the 2019 "Bloody November" and a 2026 massacre where kill orders were issued against protesters, leading to an unprecedented death toll. His family also suffered casualties in the strikes; Iranian state media confirmed the deaths of his daughter, son-in-law, and granddaughter, while Israeli media reported his son Mojtaba's death. Khamenei's compound in Tehran, used as his residence, was heavily damaged by a barrage of at least 30 bombs.

Iran swiftly responded to the US-Israeli attacks with a "crushing" wave of retaliatory missile and drone strikes across the Middle East. Targets included US military bases in Bahrain (housing the US Navy's Fifth Fleet headquarters), Kuwait, Qatar, Jordan, and the UAE (Al Dhafra air base). Iranian projectiles also hit Israeli residential areas and commercial targets in other Gulf countries, such as the Fairmont hotel and a high-rise building in Dubai, and Zayed International Airport in Abu Dhabi, resulting in casualties and damage. US Central Command (CENTCOM) reported successfully defending against hundreds of Iranian attacks, with minimal US casualties or combat-related injuries. The Iranian Revolutionary Guard also reportedly blocked ships from passing through the Strait of Hormuz, a critical oil shipping lane, in a move threatening global oil supplies.

The escalating conflict led to widespread disruption in international travel. Several countries, including Israel, Qatar, Syria, Iran, Iraq, Kuwait, Bahrain, and the UAE, closed their airspace, grounding flights and leaving hundreds of thousands of travelers stranded or diverted. Major hub airports in Dubai, Abu Dhabi, and Doha halted operations, leading to over 1,000 flight cancellations on Saturday alone, with thousands more affected globally. Airlines like Emirates, Qatar Airways, Etihad, Air India, Turkish Airlines, Delta, United, KLM, Lufthansa, Air France, and British Airways announced suspensions or reroutings, adding hours and costs to journeys. Aviation analysts warned of continued delays and cancellations, and the closure of airspace meant countries lost out on overflight fees.

Domestically, President Trump faced significant backlash from US lawmakers for launching military action without prior congressional approval, a constitutional prerequisite for war. Republicans Thomas Massie and Rand Paul, along with Democrats Ro Khanna, Ruben Gallego, and Andy Kim, condemned the strikes, calling them "illegal" and a "pointless war" that betrayed Trump's campaign promise to avoid new foreign conflicts. Former Congresswoman Marjorie Taylor Greene also criticized the move, arguing for Iranians to liberate themselves. However, Senator John Fetterman offered rare bipartisan praise for Trump's campaign. Internationally, Oman's foreign minister decried the attacks for undermining negotiations. The UN Secretary-General urged a halt to attacks and a return to diplomacy, warning of a potential wider conflict.

The strikes also sparked contrasting protests in London. Jeremy Corbyn led a pro-Iran rally in Parliament Square, condemning "Trump's wars" and carrying banners of Ayatollah Khamenei. In contrast, Iranian democracy activists gathered in Whitehall to support the US strikes, calling for the end of the Iranian government and the return of the Shah, while waving pre-Islamic regime flags. These activists, some joined by far-right activist Stephen Yaxley-Lennon, expressed hope that American and Israeli intervention would weaken the regime enough for the people to take control.

The death of Ayatollah Khamenei has created a dangerous power vacuum in Iran. While the Iranian constitution outlines a process for succession by the 88-seat Assembly of Experts, analysts indicated that the ultraconservative Islamic Revolutionary Guard Corps (IRGC) might be better positioned to consolidate power, potentially leading to a military rather than clerical government. Potential successors include Khamenei's second son, Mojtaba Khamenei, and Ali Larijani, chair of the Supreme National Security Commission. President Trump, despite launching the strikes, signaled a willingness to offer "off-ramps" to the Iranian regime to avoid further attacks, even suggesting he knew who would lead Iran next and hinting at his involvement in the selection process. However, the exact future leadership and trajectory of Iran remain highly uncertain amidst the turmoil.

Economically, the conflict is expected to cause a significant surge in global oil prices. Analysts warned that if Iran were to close the Strait of Hormuz, prices could jump to $100 a barrel, a 37% increase, leading to higher petrol costs and stoking inflation globally. This would complicate efforts by central banks, such as the Bank of England, to lower interest rates. The long-term consequences of "Operation Epic Fury" and Iran's responses are profound, marking a critical and unpredictable phase in Middle Eastern and global geopolitics.
