In a bizarre display of violence, a crowd of North Koreans have destroyed a dummy of South Korean President Lee Myung-bak.
The effigy could be seen hanging from a bridge, before an attack dog, a tank and rocks were used to tear it apart.
The display comes amid speculation the North is preparing to test a nuclear weapon for the third time. A nuclear test would showcase the North's technological skills, helping to impress a hardline military at home and buyers of North Korean weapons, one of its few viable exports.
It would come as Kim Jong-un, the third of his line to rule North Korea, seeks to cement his grip on power. North Korea has yet to show, however, that it can make a bomb small enough to fit on a missile. The recent test-launch of a long-range missile also failed.
Recently, North Korean state media has intensified its criticism of Lee Myung-bak over his remarks criticising its failed rocket launch. North Korea's state-television KRT broadcast massive anti-Lee rallies in various locations on Friday.
North and South Korea are still technically at war since the 1950-53 Korean War ended in a truce without a peace treaty.
