It seems that Tamim bin Hamad was ashamed of the heads of Arab kings who avoided dialogue with him.
In addition, the speeches delivered by the presidents at the opening of the summit dealt with the Iranian intervention in the UAE, Yemen and Turkey in Iraq, his biggest allies and supporters of the Islamic organizations in Doha and Ankara.
The Qatari Emir's sense of isolation has further heightened Egyptian President Abdel Fattah al-Sisi's arrival in Tunisia, hours after news that he was not attending the Arab summit.
According to Radio Mosaic of Tunisia, Prince Tamim left the summit immediately after the end of the speech of Tunisian President Béji Caid Sibsi and the Secretary-General of the League of Arab States.
The 30th Ordinary Session of the Arab Summit took place today in Tunis, and its chairmanship was taken by Tunisian President Béji Caid Sibsi of Saudi King Salman bin Abdulaziz.
