North Korea says its latest tests included missiles armed with cluster-bomb warheads

North Korea on Thursday said its testing spree this week involved various new weapons systems, including ballistic missiles armed with cluster-bomb warheads, as it pushes to expand nuclear-capable forces aimed at rival South Korea. The report by North Korean state media came a day after South Korea’s military said it detected North Korea firing multiple missiles from an eastern coastal area in its second round of launches in two days.
