North Korea has staged its largest ever military drill to mark the founding of the country's army, the South Korean military said.
The live-fire exercises were in the Wonsan region in the east of the country Tuesday afternoon.
A North Korean government official told CNN that it was the largest ever drill conducted by the country's military and involved 300 artillery guns.
North Korean leader Kim Jong Un gave the order to start the demonstration, where the large-caliber self-propelled guns lined up along the coast opened fire, state news agency KCNA reported Wednesday.
"Submarines rapidly submerged to make torpedo-attacks at the 'enemy' warships while fighters and bombers made zero feet flight above the sea to drop bombs on the targets," Korean Central News Agency (KCNA) said, adding that more than 300 large-caliber self-propelled guns lined up along the coast and "opened fire all at once."
