North Korean leader Kim Jong-un oversaw a live-fire artillery drill aimed at simulating an "actual war", state media said yesterday, a day after South Korea swore in its first woman president.
"An endless barrage of shells were fired by artillery pieces on 'enemy positions', their roar rocking heaven and earth, and all of them were enveloped in flames," the Korean Central News Agency said.
"Feasting his eyes at the 'enemy positions' in flames, [Kim] was satisfied," the official agency added.
KCNA gave no precise time or location for the drill, but its announcement followed Monday's presidential inauguration in the South, at which new leader Park Geun-hye signalled a "zero-tolerance" policy to provocation by North Korea.
According to KCNA, Kim ordered the live fire exercise to test the capability of artillery units "to fight an actual war". It marked the latest in a series of high-profile military inspections by Kim following the North's nuclear test earlier this month.
Last week Kim oversaw an air force demonstration, a paratrooper drill and a separate tactical attack exercise combined with live shell firing.
Kim's visits appeared to be aimed at stepping up threat levels, South Korean defence ministry spokesman Kim Min-seok said, adding that the South was watching the situation "carefully and attentively".
"The visits to military units account for about one-fifth of his public appearances made so far this year, which we believe is a bit more than past years," Kim Min-seok told reporters.
In her inauguration speech on Monday, Park demanded that Pyongyang "abandon its nuclear ambitions" immediately and warned that the North's test was a challenge to the future survival of the Korean people.
