the Shah took an armored column to Qom, and delivered a speech harshly attacking the ulama as a class. Khomeini continued his denunciation of the Shah's programmes, issuing a manifesto that bore the signatures of eight other senior Shia religious scholars. Khomeini's manifesto argued that the Shah had violated the constitution in various ways, he condemned the spread of moral corruption in the country, and accused the Shah of submission to the United States and Israel. He also decreed that the Nowruz celebrations for the Iranian year 1342 (which fell on 21 March 1963) be canceled as a sign of protest against government policies. On the afternoon of 'Ashura (3 June 1963), Khomeini delivered a speech at the Feyziyeh madrasah drawing parallels between the Sunni Muslim caliph Yazid, who is perceived as a 'tyrant' by Shias, and the Shah, denouncing the Shah as a "wretched, miserable man," and warning him that if he did not change his ways the day would come when the people would offer up thanks for his departure from the country. On 5 June 1963 (15 of Khordad) at 3:00 am, two days after this public denunciation of the Shah, Khomeini was detained in Qom and transferred to Tehran. Following this action, there were three days of major riots throughout Iran and the deaths of some 400 people. That event is now referred to as the Movement of 15 Khordad. Khomeini remained under house arrest until August. Opposition to capitulation On 26 October 1964, Khomeini denounced both the Shah and the United States. This time it was in response to the "capitulations" or diplomatic immunity granted by the Shah to American military personnel in Iran.Shirley, Know Thine Enemy (1997), p. 207. What Khomeini labeled a capitulation law, was in fact a "status-of-forces agreement", stipulating that U.S. servicemen facing criminal charges stemming from a deployment in Iran, were to be tried before a U.S. court martial, not an Iranian court. Khomeini was arrested in November 1964 and held for half a year. Upon his release, Khomeini was brought before Prime Minister Hassan Ali Mansur, who tried to convince him to apologize for his harsh rhetoric and going forward, cease his opposition to the Shah and his government. When Khomeini refused, Mansur slapped him in the face in a fit of rage. Two months later, Mansur was assassinated on his way to parliament. Four members of the Fadayan-e
