A state of emergency and accompanying curfew were declared throughout the Malaysia. The curfew was relaxed in most parts of the country for two hours. The National Operations Council (NOC) was established by proclamation of the Yang di-Pertuan Agong (King of Malaysia) Sultan Ismail Nasiruddin Shah, headed by Tun Abdul Razak. With Parliament suspended, the NOC became the supreme decision-making body for the next 18 months. State and District Operations Councils took over state and local government. The NOC implemented security measures to restore law and order in the country. Curfews continued in most parts of the country, but were gradually scaled back. Peace was restored in the affected areas within two months.
