North Korean leader salutes as his army fires rockets and torpedoes at mock enemy warships during country's 'largest ever' live-fire artillery drills

Kim Jong-Un's army readied for war as they fired rockets and torpedoes at mock enemy warships during North Korea's 'largest ever' live-fire artillery drills on Tuesday.

Hundreds of tanks were lined up along the eastern coastal town of Wonsan in a show of military strength to celebrate 85 years since the North Korean army was created.

Kim saluted the military as he watched the exercises on Tuesday, which involved the firing of more than 300 large-calibre artillery pieces and included submarine torpedo-attacks.

Just one day later, South Korea conducted joint military live-fire drills with the US at Seungjin fire training field in Pocheon, South Korea, near the border with North Korea.
