Lala Kara Mustafa Pasha, the Ottoman governor of Syria, was ordered by Selim II to suppress the Yemeni rebels. However, the Turkish army in Egypt was reluctant to go to Yemen due to their knowledge of the hegemony of the northern Yemenis. Mustafa Pasha sent a letter with two Turkish ''shawishes'' hoping to persuade al-Mutahhar to give an apology and confirm that Mustafa Pasha did not promote any act of aggression against the Ottoman army, and state that the "ignorant Arabian" according to the Turks, acted on their own. Imam al-Mutahhar refused the Ottoman offer. When Mustafa Pasha sent an expeditionary force under the command of Uthman Pasha, it was defeated with great casualties. Sultan Selim II was infuriated by Mustafa's hesitation to go to Yemen. He executed a number of ''sanjak-beys'' in Egypt and ordered Sinan Pasha to lead the entire Turkish army in Egypt to reconquer Yemen. Sinan Pasha was a prominent Ottoman general of Albanian origin. He reconquered Aden, Taiz, and Ibb, and besieged Shibam Kawkaban in 1570 for seven months. The siege was lifted once a truce was reached. Imam al-Mutahhar was pushed back, but could not be entirely overcome. After al-Mutahhar's demise in 1572, the Zaydi community was not united under an imam; the Turks took advantage of their disunity and conquered Sana'a, Sa'dah, and Najran in 1583. Imam al-Nasir Hassan was arrested in 1585 and exiled to Constantinople, thereby putting an end to the Yemeni rebellion.
