HONOLULU — State authorities won’t sound sirens warning of a nuclear missile attack during a monthly test this week.

The decision comes after an agency employee in January mistakenly sent cellphone and broadcast alerts warning of an incoming ballistic missile.

Instead, Hawaii Emergency Management Agency officials only plan to test a separate siren that warns of tsunamis and other natural disasters. The test is scheduled for today.

Brig. Gen. Kenneth Hara last week recommended the agency suspend its missile attack outreach until it prepares a report about how the state should respond to a chemical, biological, radiological or nuclear attack or accident.

Hara didn’t recommended suspending the missile siren tests. But state Department of Defense spokesman Lt. Col. Charles Anthony says the agency decided to stop them as well.
