US states revive civil defence plans in wake of N Korea tests

The bellicose relationship between US President Donald Trump and North Korea’s leader, Kim Jong-un, has US states looking to Cold War civil defence plans, as fears of war between the two increase.

In the wake of North Korea’s latest missile test, Hawaii has tested its nuclear warning sirens.

The US is updating old civil defence plans and systems that date back to the Cold War.

The threats and bluster between Donald Trump and Kim Jong-un have many worried about a revived nuclear threat.
