North Korean leader Kim Jong-Un oversaw a live-fire artillery drill aimed at simulating an "actual war", state media said just a day after South Korea swore in its first female 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 (KCNA) said on Tuesday.
"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 North Korea provocation.
According to KCNA, Kim ordered the live fire exercise to test the capability of artillery units "to fight an actual war".
