Following the official announcement of Kim Jong Il's death today, North Korea has imposed rigid social controls, including the complete closure of markets.

An inside source told Daily NK this lunchtime, "The jangmadang is closed and people are not allowed to go outside. Local Party secretaries are issuing special commands through local Union of Democratic Women unit chairwomen, and the chairwomen have been gathered at district offices for emergency meetings."

According to the source, National Security Agency and People’s Safety Ministry agents have been deployed in streets and alleyways to control civilian movements. There have not been any signs of public unrest to date.

Kim Jong Il's sudden death has apparently caught people off-guard, the source revealed, commenting, "Nobody had the slightest idea about the General’s death even right before they saw the broadcast. You can hear the sound of wailing outside."
