North Korea tests third nuclear device

North Korea conducted a third underground nuclear test yesterday, further compounding the already tense situation on the Korean Peninsula and across North East Asia.
The official KCNA news agency announced that scientists had conducted a successful test of “a miniaturised and lighter nuclear device with greater explosive force.” Estimates, based on seismic data, put the size of the blast at between 7 and 10 kilotons. This is larger than two previous tests in 2006 and 2009, and about half the yield of the US bombs dropped on Hiroshima and Nagasaki.
