passengers – 9 million for Terminal 1 and 3 million for Terminal 2. There are frequent air flights by including Malaysia Airlines (MAS) and AirAsia between East Malaysia and Peninsular Malaysia. Other ports of entry to East Malaysia include Sibu Airport, Bintulu Airport, and Miri Airport in Sarawak, Sandakan Airport and Tawau Airport in Sabah. MAS also operates international flights to major cities in East Malaysia. The rural areas in Borneo can only be accessed by air or river boat. River transport is especially prevalent in Sarawak because there are many large and long rivers, with Rajang River being the most used. Rivers are used by boats and ferries for communications (i.e. mail) and passenger transport between inland areas and coastal towns. Timber is also transported via vessels and log carriers down the rivers of Sarawak. The Labuan Ferry operates boat express and vehicle ferries from Labuan Island to Sabah, Sarawak and Brunei. Ferries have overtaken air travel as the chief transportation mode on and off the island. Economy Shipyards in Sabah and Sarawak build steel vessels for offshore supply, tug, barge and river ferries when compared to shipyards in Peninsular Malaysia that focus on building steel and aluminium vessels for the government as well as oil and gas companies. This makes the shipyards in Sabah and Sarawak more competitive and innovative in design, process and material, compared to the shipyards in peninsular Malaysia, where the big projects are dependent on government funding. Security The state of Sabah has been subjected to attacks by Moro pirates and militants since the 1960s and intensification in 1985, 2000, 2013. The Eastern Sabah Security Zone (ESSZONE) and Eastern Sabah Security Command (ESSCOM) were established on 25 March 2013 to tighten security in the region. Since 2014, a 12-hour dusk-to-dawn curfew has been imposed on six Sabah east coast districts.
