More about the son of Khamenei and Khazali:
The third link between Mojtaba Khamenei and the paramilitary groups is Hassan Taeb, the current commander of the Basij. A hardliner and cleric, he is also linked with Mesbah Yazdi and his followers.
So through these three links — Ayatollah Aziz Khoshvaght, Brigadier General Mohammad Hejazi and Hassan Taeb — Mojtaba Khamenei is connected with the forces that crack down on protesters and demonstrators. Though little is officially known about the political views of Mojtaba Khamenei, it would not be a stretch to put him in the radical right-wing camp hellbent on advancing the agenda of extremists such as Mesbah Yazdi and Khazali to establish the so-called Islamic government, as opposed to an Islamic Republic, where the views and votes of the people matter.
Mojtaba has always been around the ultraconservatives. He has been educated by them, and has been close to radical right-wing groups. He has had close friendships with notorious figures such as Saeed Emami, and reactionaries such as Mesbah Yazdi, Khazali and Kharrazi. He is known to be fiercely opposed to the reform movement and its leaders.
