began military training near Halim Air Force Base; the concept of arming the people had won support among the Air Force and the Navy. On 8 September, PKI demonstrators began a two-day siege of the U.S. consulate in Surabaya. Aidit addressed a PKI rally on 14 September, urging members to be alert for things to come. On 30 September, Pemuda Rakyat and Gerwani (both PKI-associated organizations) held a mass rally in Jakarta to protest the inflation crisis. 30 September movement During the night of 30 September and 1 October 1965, six of Indonesia's top army generals were killed and their bodies thrown down a well. The generals' killers announced the following morning that a new Revolutionary Council had seized power, calling themselves the "30 September Movement" ("G30S"). With much of the army's top leadership dead or missing, General Suharto took control of the army and put down the abortive coup by 2 October. The army quickly blamed the coup attempt on the PKI, and began an Indonesia-wide anti-Communist propaganda campaign. Evidence linking the PKI to the generals' assassinations is inconclusive, leading to speculation that their involvement was very limited or that Suharto organised the events (in whole or in part) and scapegoated the communists. In the ensuing violent anti-communist purge, an estimated 500,000 communists (real and suspected) were killed and the PKI effectively eliminated. General Suharto outmaneuvered Sukarno politically and was appointed president in 1968, consolidating his influence on the military and government. On 2 October, the Halim base was recaptured by the army. Although Harian Rakyat carried an article in support of the G30S coup, the official PKI line at the time was that the attempted coup was an internal affair within the armed forces. On 6 October, Sukarno's cabinet held its first meeting since 30 September; the PKI minister Njoto was in attendance. A resolution denouncing G30S was passed, and Njoto was arrested immediately after the meeting. A mass demonstration was held in Jakarta two days later demanding a ban on the PKI, and the party's main office was burned down. On 13 October, Ansor Youth Movement (the youth wing of Nahdlatul Ulama) held anti-PKI rallies across Java. Five days later, Ansor killed about a hundred PKI members. Mass killings Between 100,000 and two million Indonesians were killed in the mass killings that followed. The victims included non-Communists who were slain because of mistaken identity or guilt by
