2026 in Iran

On 28 February 2026, the United States and Israel launched airstrikes on Iran targeting military and government sites and assassinating several Iranian officials, including Supreme Leader Ali Khamenei. The surprise attacks were launched during negotiations between Iran and the US regarding Iran's nuclear program. Iran responded with missile and drone strikes against Israel, US bases, and US-allied Arab countries in the Middle East, and the closure of the Strait of Hormuz, disrupting global trade.

The 2025–2026 Iranian protests are a series of nationwide demonstrations against the government of Iran that began on 28 December 2025 amid a deepening economic crisis. The unrest followed a sharp depreciation of the Iranian rial, rising inflation, and widespread shortages linked to international sanctions and government mismanagement. This event has been the largest uprising in Iran since the 1979 Islamic Revolution, spreading to more than 200 cities across the country. The ensuing crackdown, reportedly carried out under orders by Ali Khamenei and senior officials to use live fire on protesters, resulted in massacres that left thousands of protesters dead, making them the largest massacres in modern Iranian history.

Shipping traffic through the Strait of Hormuz, a major maritime choke point for world energy trade, has been largely blocked by Iran since 28 February 2026, when the United States and Israel launched an air war against Iran and assassinated its supreme leader Ali Khamenei. In retaliation, Iran launched missile and drone attacks on Israel, US military bases, and US-allied Gulf states. The Iranian Revolutionary Guard (IRGC) issued warnings forbidding passage through the strait, has boarded and attacked merchant ships, and has laid sea mines in the strait. Since 13 April, the US has blockaded Iranian ports, leading to a "dual blockade" of the strait. Until the US–Israeli war against Iran, the Strait of Hormuz was open and about 25% of the world's seaborne oil trade and 20% of the world's liquefied natural gas (LNG) passed through it.
