Residents of Guam have been issued with advice on what to do if North Korea launches an attack.

The guidance includes taking cover quickly in a concrete structure, preferably underground.

The factsheet, issued by Guam's Office of Civil Defence and titled Preparing for an Imminent Missile Threat, advises people not to look at the flash of a fireball because it could cause blindness.

It also includes guidance on removing radioactive material, saying: "When possible, take a shower with lots of soap and water to help remove radioactive contamination.

"But don't scratch or scrub skin and do not use conditioner in your hair because it will bind radioactive material to your hair."
