North Korea has turned up efforts in recent weeks to ensure the younger generation remains obedient to leader Kim Jong Un, holding a cross-country loyalty march and a ceremony at which youth presented “Kid” rocket launchers to the military to celebrate the anniversary of the Korean Children’s Union (KCU).

According to Korean Central News Agency (KCNA), a ceremony to pass on the KCU’s symbolic letter vowing to “trust and follow only the respected fatherly Marshal Kim Jong Un” took place Monday at the Mangyongdae Revolutionary School.
