Neither missile hit its target, the Diego Garcia base.

The first missile failed, and the second was apparently hit by an SM-3 interceptor fired by a US warship.

The missile launches were reported by The Wall Street Journal on Friday.

It's unclear when the missiles were fired.

The New York Post reports that the missile launches have "worried experts who believe the rogue nation's long-range missile capabilities have increased despite a reported self-ban on missiles that can go further than 1,200 miles."

Days before he launched Operation Epic Fury, President Trump said Iran was developing missiles that could reach the US.

In his State of the Union address, he said of Iran, "They've already developed missiles that can threaten Europe and our bases overseas, and they're working to build missiles that will soon reach the United States of America."

Diego Garcia, a British Indian Ocean Territory, is the largest island in the Chagos archipelago.

American bombers, nuclear submarines and guided-missile destroyers are based there.

B-1 Lancer bombers have now been moved to Diego Garcia, for strikes against Iran.

On Friday, UK Prime Minister Keir Starmer gave the US permission to launch strikes on Iran from Diego Garcia and from RAF Fairford in Gloucestershire, England.

Starmer had previously denied US access to these bases, but now says they can be used for the "collective self-defense" of the Strait of Hormuz, through which 20% of the world's oil exports normally pass.
