Hawaii missile alert: False alarm warning broadcast

14 January 2018 Last updated at 02:40 GMT

An incoming missile alert plunged residents of Hawaii into panic on Saturday morning before it was declared to be false.

An alert system is in place because of the potential proximity of Hawaii to North Korean missiles.

In December, the state tested its nuclear warning siren for the first time since the end of the Cold War.
