While an intensive investigation of the massive crowd crush in Itaewon is underway, communication failures between the government's emergency-related agencies are being pointed to as one of the major reasons behind the government's inadequate response to the disaster. At least 156 people were killed and nearly 200 were injured in the crowd crush that occurred during the Halloween festivities in Itaewon, Yongsan District in Seoul, on the night of Oct. 29.
