North Korea on Thursday dismantled its nuclear testing site at Punggye-ri, the Associated Press reported, in a public event attended by 30 international journalists.

Further details on the demolition are expected in the next few hours, with initial reports from South Korean press pool members who attended the event saying its decommissioning began at 1100 and continued until 1617 local time. However, CNN reported that tunnels two, three and four at the site, had been destroyed.
