North Korean leader Kim Jong Un made another inspection tour of major munitions factories and ordered a drastic increase in production of missiles and other weapons, state media said Monday, days before South Korea and the US begin annual military drills that North Korea views as an invasion rehearsal.

Kim's push to produce more weapons also comes as US officials believe Russia's defence minister recently talked with North Korea about selling more weapons to Russia for its war with Ukraine. The Korean Central News Agency said Kim visited factories producing tactical missiles, mobile launch platforms, armoured vehicles and artillery shells on Friday and Saturday.
