Al-Gama'a al-Islamiyya
The 1991 killing of the group's leader, Ala Mohieddin, presumably by security forces, led Al-Gama'a al-Islamiyya to murder Egypt's speaker of parliament in retaliation. In June 1995, working together with Egyptian Islamic Jihad, the group staged a carefully planned attempt on the life of President Mubarak, led by Mustafa Hamza, a senior Egyptian member of the Al-Qaeda and commander of the military branch of the Al-Gama'a al-Islamiyya. Mubarak escaped unharmed and retaliated with a massive and ruthless crackdown on GI members and their families in Egypt.
