North Korea carried out its most powerful nuclear test to date on Sunday, claiming to have developed an advanced hydrogen bomb that could sit atop an intercontinental ballistic missile.
The bomb used in the country’s sixth-ever nuclear test sent tremors across the region that were 10 times more powerful than Pyongyang’s previous test a year ago, Japanese officials said.
While the type of bomb used and its size have not been independently verified, if true, the pariah state is a significant step closer to being able to fire a nuclear warhead to the US mainland, as it has repeatedly threatened it could if provoked.
Pyongyang has ratcheted up its ballistic missile testing this year and engaged in a fiery exchange of threats with US President Donald Trump. It has developed projectiles that it says could reach the US mainland, and some experts agree that’s likely true.
