Early on March 16, 2026, severe US-Israeli airstrikes targeted strategic infrastructure across multiple Iranian cities, destroying air defense systems and heavily damaging Mehrabad Airport and fuel depots in Tehran. In retaliation, Iran launched widespread missile and drone attacks that triggered sirens across central Israel, struck a fuel depot at Dubai International Airport causing temporary flight suspensions, and targeted Saudi Arabia's Prince Sultan Air Base. Concurrently, Iraqi resistance forces fired missiles at the US Camp Victoria base in Baghdad, and air defenses intercepted a drone near the US Embassy. Amid the escalating conflict, foreign maritime traffic through the Strait of Hormuz halted completely, while key US allies, including the UK, Germany, and Japan, formally rejected President Donald Trump's requests to join a naval coalition to reopen the waterway. On the northern front, Israel's 91st Division initiated limited ground operations against Hezbollah in southern Lebanon. Domestically, the Iranian judiciary ordered the asset confiscation of suspected foreign collaborators as major state banks suffered widespread online service outages following the morning bombardments.
