North Korea has released images of live fire drills to mark the 85th anniversary of the founding of the country's army.
Video of the day shows North Korean leader Kim Jong-un striking a defiant pose as he attended what was described by official media as his country’s largest ever live fire drill.
“More than 300 large-caliber self-propelled guns” took part in the massive show of force, the North’s KCNA news agency said in its report on the huge display of firepower, that was staged amid escalating tensions in north-east Asia.
Kim supervised the exercises, which saw artillery units, navy and airforce vehicles taking part, and involved submarines firing torpedos, KCNA said.
"The brave artillerymen mercilessly and satisfactorily hit the targets and the gunshots were very correct, he said, adding that they showed well the volley of gunfire of our a-match-for-a-hundred artillery force giving merciless punishment to the hostile forces," KCNA added.
Forces from the United States and South Korea have also been carrying out manouvres this week, while Japanese warships have conducted drills with a US aircraft carrier strike group.
