In 1971, Al-Aloul was arrested by Israel for terrorist activities during the Six-Day War and expelled to Jordan. In Jordan, he became involved in the establishment of the Fatah movement and, in the late 1970’s al-Aloul moved to Lebanon. In 1983, as commander of a Fatah military brigade, al-Aloul oversaw the abduction of six Israeli soldiers in Lebanon and then successfully ransomed them for the release of more than 5,000 prisoners from the Ansar detention camp and 100 prisoners from Israeli prisons.
Upon returning to the West Bank in 1994, al-Aloul was appointed Governor of Nablus by Yasser Arafat. Al-Aloul was elected to the Fatah Central Committee in 2009, and was appointed Deputy Party Leader of Fatah in 2017.
His son, Jihad al-Aloul, was killed in clashes with Israeli soldiers during the Second Intifada.
