TOPSHOT - CORRECTION / An Emirates Boeing 777 aircraft prepares for landing as a smoke plume rises from an ongoing fire near Dubai International Airport in Dubai on March 16, 2026. Flights were gradually resuming at Dubai airport on March 16, previously the world's busiest for international flights, the airport operator said, after a "drone-related incident" sparked a fuel tank fire nearby, as Iran kept up its Gulf attacks.

What happened

The United Arab Emirates said Wednesday it had halted “all trade, commercial exchanges and financial transactions” with Iran “until future notice” due to “escalations that undermine regional and international peace and security.” Hours earlier, the UAE had accused Tehran of firing two missiles into its territory. Iran’s Foreign Ministry called that accusation “baseless” and possibly a “false flag operation.”

Iranian Gen. Ali Abdollahi later warned “countries on the southern shores of the Persian Gulf” that “any assistance” given to the U.S. military “amounts to participation” in its war. President Donald Trump on Wednesday night threatened that “ANY country that allows its financial institutions” or other entities to “provide any type of lifeline to Iran will itself face TREMENDOUS Economic Consequences.”

Who said what

The UAE is one of Tehran’s “biggest economic lifelines,” The Wall Street Journal said, and Trump’s “effort to squeeze Iran into submission will depend heavily” on Dubai. It’s unclear if the U.S. “played a role in the embargo decision,” The New York Times said, but it was announced “hours after a call” from Trump to the Emirati leader.

What next?

If “implemented broadly,” the UAE’s trade severance could significantly harm Iran’s economy, the Journal said. But “severing those links will be difficult” and “could hurt Dubai’s role as a freewheeling global hub for commerce.”
