North Korea's leader Kim Jong-Un has reportedly ordered the execution of five senior security officials - with a gun usually used to bring down aircraft.
The five officials were reportedly executed because they made false reports to Kim about the state of the country's military.
The head of the same department was fired last month, amid claims of torture committed by his agency.
The executions are not thought to be related to the ongoing investigation into the death of Kim's half-brother in Malaysia earlier this month.
