Iran’s Revolutionary Guard shot down a U.S. drone on Thursday amid heightened tensions between Tehran and Washington over the collapsing nuclear deal with world powers, American and Iranian officials said, though they disputed the circumstances of the incident.
The Guard said it shot down the RQ-4 Global Hawk drone over Iranian airspace, while the U.S. said the downing happened over international airspace in the Strait of Hormuz. Later, the U.S. military’s Central Command released a statement calling the downing an “unprovoked attack.”
Previously, the U.S. military alleged that Iran had fired a missile at another drone last week that was responding to the attack on two oil tankers near the Gulf of Oman. The U.S. blames Iran for the attack on the ships; Tehran denies it was involved.
Separately, Saudi Arabia said on Thursday that Yemen’s Iranian-allied Houthi rebels launched a rocket targeting a desalination plant in the kingdom the previous night. The White House said Trump was briefed about that attack.
Iran has quadrupled its production of low-enriched uranium and threatened to boost its enrichment closer to weapons-grade levels, trying to pressure Europe for new terms to the 2015 nuclear deal.
In recent weeks, the U.S. has sped an aircraft carrier to the Mideast and deployed additional troops alongside the tens of thousands already in the region. From Yemen, the Houthis have launched bomb-laden drones into neighboring Saudi Arabia.
All this has raised fears that a miscalculation or further rise in tensions could push the U.S. and Iran into an open conflict, some 40 years after Tehran’s Islamic Revolution. Thursday’s drone incident marks the first direct Iranian-claimed attack on the U.S. amid the crisis.
“We do not have any intention for war with any country, but we are fully ready for war,” Revolutionary Guard commander Gen. Hossein Salami said in a televised address.
Iran’s paramilitary Revolutionary Guard, which answers only to Supreme Leader Ayatollah Ali Khamenei, said it shot down the drone on Thursday morning when it entered Iranian airspace near the Kouhmobarak district in southern Iran’s Hormozgan province. Kouhmobarak is some 750 miles southeast of Tehran and close to the Strait of Hormuz.
The Guard said it shot down the drone at 4:05 a.m. after it collected data from Iranian territory, including the southern port of Chahbahar near Iran’s border with Pakistan. Iran used its air defense system known as Third of Khordad to shoot down the drone — a truck-based missile system that can fire up to 18 miles into the sky, the semi-official Fars news agency reported.
Iran’s state-run IRNA news agency, citing the Guard, identified the drone as an RQ-4 Global Hawk, which cost over $100 million apiece and can fly higher than 10 miles in altitude and stay in the air for over 24 hours at a time. They have a distinguishable hump-shaped front and an engine atop. Their wingspan is bigger than a Boeing 737 passenger jet.
The Guard described the drone as being launched from the southern Persian Gulf but did not elaborate. American RQ-4 Global Hawks are stationed at the Al-Dhafra Air Base in the United Arab Emirates, near the capital, Abu Dhabi. AP journalists saw the drones on the base’s tarmac during a March 2016 visit by then-Vice President Joe Biden.
The CENTCOM statement said the RQ-4A Global Hawk maritime surveillance drone was shot down by an Iranian surface-to-air missile while in international airspace over the Strait of Hormuz, the narrow mouth of the Persian Gulf through which 20% of all global oil moves.
The U.S. has been worried about international shipping through the Strait of Hormuz since the limpet mine attacks in May and June.
“Iranian reports that the aircraft was over Iran are false,” CENTCOM said, adding that “this was an unprovoked attack on a U.S. surveillance asset in international airspace.”
White House spokeswoman Sarah Sanders said Trump had been briefed. “We are closely monitoring the situation and continuing to consult with our partners and allies,” she said.
