On 15 September 1970, the PFLP (part of the PLO) hijacked four planes and landed three of them at Dawson's Field, located east of Amman. After the foreign national hostages were taken off the planes and moved away from them, three of the planes were blown up in front of international press, which took photos of the explosion. This tarnished Arafat's image in many western nations, including the United States, who held him responsible for controlling Palestinian factions that belonged to the PLO. Arafat, bowing to pressure from Arab governments, publicly condemned the hijackings and suspended the PFLP from any guerrilla actions for a few weeks. He had taken the same action after the PFLP attacked Athens Airport. The Jordanian government moved to regain control over its territory, and the next day, King Hussein declared martial law. On the same day, Arafat became supreme commander of the PLA. As the conflict raged, other Arab governments attempted to negotiate a peaceful resolution. As part of this effort, Gamal Abdel Nasser led the first emergency Arab League summit in Cairo on 21 September. Arafat's speech drew sympathy from attending Arab leaders. Other heads of state took sides against Hussein, among them Muammar Gaddafi, who mocked him and his schizophrenic father King Talal. A ceasefire was agreed upon between the two sides, but Nasser died of a massive heart attack hours after the summit, and the conflict resumed shortly afterward. By 25 September, the Jordanian Army achieved dominance, and two days later Arafat and Hussein agreed to a ceasefire in Amman. The Jordanian Army inflicted heavy casualties on the Palestinians—including civilians—who suffered approximately 3,500 fatalities. After repeated violations of the ceasefire from both the PLO and the Jordanian Army, Arafat called for King Hussein to be toppled. Responding to the threat, in June 1971, Hussein ordered his forces to oust all remaining Palestinian fighters in northern Jordan, which they accomplished. Arafat and a number of his forces, including two high-ranking commanders, Abu Iyad and Abu Jihad, were forced into the northern corner of Jordan. They relocated near the town of Jerash, near the border with Syria. With the help of Munib Masri, a pro-Palestinian Jordanian cabinet member, and Fahd al-Khomeimi, the Saudi ambassador to Jordan, Arafat managed to enter Syria with nearly two thousand of his fighters. However, due to the hostility of relations between Arafat and Syrian President Hafez al-Assad (who had
