An app alert warned residents in Hawaii that a BALLISTIC MISSILE was heading straight for them.
Residents and tourists ran for shelter as hundreds of phones reportedly received the terrifying message.
Broadcasters interrupted a basketball game on US channel CBS to announce there a missile could be about to hit the state.
The alert, written all in block capitals, read: ‘BALLISTIC MISSILE THREAT INBOUND TO HAWAII.
‘SEEK IMMEDIATE SHELTER. THIS IS NOT A DRILL’.
The message turned out to be a false alarm and investigations are said to be underway into what caused it to be sent out on Saturday.
A screen shot shared online suggests terrified tourists fled to their hotel basement in fear of an imminent attack.
“Just got an emergency alert for Hawaii,” it read.
“We’re all in the basement of hotel.”
Hawaii congresswoman Tulsi Gabbard tweeted that the message was a false alarm.
“This is a false alarm”, she said. There is no incoming missile to Hawaii. I have confirmed this with officials. There is no incoming missile.”
Hawaii would be in the flight path between North Korea and the US.
The warning alert came after months of nerve-inducing intercontinental ballistic missile tests by Kim Jong Un.
