WATCH: Hawaii tests Cold War-era nuclear warning siren

Hawaii tested out a Cold War-era nuclear warning siren on Friday, just days after North Korea conducted its latest missile test, which the regime claims is a new type of ballistic missile that is capable of striking any part of the U.S. mainland.

The state is the first to test the warning system, which has not been used since the end of the Cold War, and is an attempt to prepare those on the island for a nuclear attack, amid rising tensions with Pyongyang.
