A week after his arrival in Turkey, Khomeini was sent to Bursa and he stayed there for eleven months. He was hosted by a colonel in the Turkish Military intelligence named Ali Cetiner in his own residence.[17] According to Turkish law, clerical dress was banned and Khomeini was never allowed to meet people. On 3 December 1964, his son, Mostafa, joined him.[18] In his first days in Turkey, Khomeini was extremely angry at the secular dress of Turkish women, but he learned to adapt quickly to his new surroundings.[19] Despite the bans on contact with Khomeini, he and his students – most notably future President Akbar Hashemi Rafsanjani – would plot the successful assassination of Prime Minister Hassan-Ali Mansur as soon as Khomeini left Iran.[4]
