THE dangerous game of bluff between North Korea and South Korea has intensified since an exchange of artillery fire across the border on Thursday.
Yesterday, North Korean leader Kim Jong-un ordered his frontline troops to be in a "wartime state ... fully battle ready to launch surprise operations", North Korea's official KCNA news agency reported.
According to the South's defence ministry, North Korea started the artillery exchange by firing rounds at one of the South's loudspeaker units. The South responded with dozens of rounds of 155mm shells.
North Korea had previously warned the South to dismantle loudspeakers blasting propaganda messages across the border or face military action.
Speaker broadcasts were resumed by the South this month for the first time since 2004, after landmine explosions in the demilitarised zone wounded two South Korean soldiers.
Despite the threat of nuclear conflict, North Korea has been ramping up the threats as US and South Korean military forces conduct their annual joint exercises.
