The Hawaii Emergency Management Agency confirmed on Saturday that there was no ballistic missile headed toward the state, minutes after an emergency alert was sent to cellphones urging people to seek immediate shelter.
The episode came at a time of heightened tensions with North Korea, which has said that it has successfully tested ballistic missiles capable of reaching the United States.
Representative Tulsi Gabbard, Democrat of Hawaii, tweeted that she had confirmed with the authorities that there was no missile en route.
Cmdr. David Benham, a spokesman for the United States Pacific Command, said in an emailed statement: “USPACOM has detected no ballistic missile threat to Hawaii. Earlier message was sent in error. State of Hawaii will send out a correction message as soon as possible.”
The false alarm caused widespread panic on social media.
