Residents of Hawaii were thrown into a panic Saturday morning after an emergency alert was sent warning of a ballistic missile threat. But officials minutes later said it was a false alarm. "NO missile threat to Hawaii," the state's Emergency Management Agency tweeted at 8:20 local time (1:20 ET). Rep. Tulsi Gabbard, D-Hawaii, tweeted: "This is a false alarm. There is no incoming missile to Hawaii." The unintended alert comes after Hawaiian officials in November said they were reinstating air raid warning sirens because of rising tensions between the U.S. and North Korea. The Pentagon did not immediately respond to requests for comment.
