In Java, forest fires burned in West Java and Mount Merapi, Central Java. A forest fire, which trapped hikers and killed at least seven of them on Mount Lawu in Magetan Regency in East Java, was later reported to have been caused by a bonfire. This incident caused local areas to be evacuated. The haze in Palangkaraya was so thick that it turned the air yellow and exceeded the 'dangerous' threshold by 10 times. The annual parliamentary meeting was interrupted, as the smoke from outside entered the room, causing all of the politicians to use masks and tissues in the room. Most schools in the affected area were closed until further notice due to the haze. In Riau and Palembang, students were advised to go to school only twice a week. Sometimes they did not even go to school for a whole week due to the haze, causing wide concern among parents and government officials. At least ten companies, seven of which are foreign companies, were declared as the prime suspects for fire in Sumatra and Kalimantan. Two of the companies' certificates were suspended by the government. Indonesian president Joko Widodo ordered all hospitals and puskesmas (community health clinics) to be open for 24 hours. On 20 October, there were 825 new hotspots in Sumatra, with the visibility in Riau deteriorating to 50 meters. Around 66 flights in Pekanbaru were cancelled. At noon, the haze worsened as the air became yellow. The Government of Riau, later made a statement that the haze crisis has killed their citizens slowly by suffocating them.
