A US state has revealed how it is preparing for a North Korean nuclear attack – amid fears missiles will take just 20 minutes to reach the coast.

Emergency planners in Alaska have warned it will not attempt evacuations if a warhead is fired.

Jeremy Zidek, from the state’s disaster planning team, will urge locals to find shelter rather than risk being caught in the open.

He also urged families to have an emergency stash of food and water, flashlights and radios, and medical supplies including the anti-radiation pill Prussian Blue – medication that lessens the radiological impacts on your body.

Tensions have escalated on the Korean peninsula after a series of missile tests in the hermit kingdom.

Tubby tyrant Kim Jong-un has since threatened a “nuclear holocaust” and there are fears the regime will soon have a missile capable of reaching the US mainland.

Mr Zidek admitted that the state’s defensive facilities could be picked for attack.

Alaska is home to Fort Greely, where the US has interceptor rockets designed to destroy incoming intercontinental ballistic missiles (ICBMs).

The state also has missile defences at the Pacific Spaceport Complex as well as radar warning systems at Clear Air Force Station.

Mr Zidek said: “We have the missile defence system here. We have missiles and radars in number of different locations.”

“Perhaps there would be some type of attack on those military facilities to try to hinder our ability to react to any missile launches.”

He also warned that Alaska no longer retains bomb shelters and there would be no new measures to deal specifically with the nuclear threat.

He said: “There could be evacuation notices put in place but are we going to be able to get that amount of lead time to instruct people to actually evacuate an area?

“Really the recommendation for people during a nuclear attack is to shelter in place and find some type of secure location that will protect them from that blast.

“So with a mass evacuation – if people leave their homes, schools and businesses to try to get out of the area, we may be putting more people at risk.”

Emergency planners in Hawaii have already confirmed that their state is within 20 minutes of Kim Jong-un’s missiles – and Alaska is even closer.

Guam is the closest US territory to North Korea – and Attu Island, the westernmost point in Alaska, is barely 50 miles further away.

Anchorage, the state’s largest city, is nearly 1000 miles closer to Kim’s kingdom than the Hawaiian capital, Honolulu.

Earlier this year, Kim said he was “carefully considering” a strike on Guam and US President Donald Trump was forced to come to the territory’s defence.

Mr Zidek said Alaska had reviewed its radiological threat plans and prepared social media warnings to be published at short notice.

Otherwise, he said Alaska would respond to a nuclear attack using the same plans already devised for disasters like earthquakes and volcanic eruptions.

He continued: “The thing with disasters is – while disasters may vary a great deal – the consequences of the disasters don’t really change very much.

“With something like a nuclear attack, of course you’re going to have mass casualties, a hazmat event, and you’re gonna have the need to transport a large number of people.

“When we look at these problems, the consequences of the attack, they may be the same as if we had another large earthquake or we have a massive chemical spill.”

He added: “On a state level, when we look at our all-hazards plan, we say to ourselves ‘we are preparing for the consequences of any type of disaster’.

“And that’s exactly what we want our residents here in Alaska to do. Prepare for the consequences of any type of disaster.”
