South Korean police and military officials have launched a joint investigation into a letter threatening to “execute” the country´s defence minister, officials said today.
The letter and a kitchen knife were found by a delivery man last week when he tried to re-pack a torn parcel addressed to Defence Minister Han Min-Koo, the defence ministry said.
“Through our investigation, we are trying to determine whether North Korea has been involved,” a ministry spokesman told.
The minister has vowed to take strong action against any provocations by North Korea, which has conducted a series of missile and rocket tests in recent months.
