Niser bin Muhammad Nasr Nawar

Nawar remained in Canada until February 2002, when he and several others traveled to Tunisia to prepare for the attack. He told his family that the others were from the travel agency.

Early on 11 April 2002, he and a colleague drove the truck loaded with natural gas canisters behind a German tourist bus near the synagogue. Nawar then used a cell phone belonging to his brother, to phone Christian Ganczarski, whom he asked to pray for him. He also had a phone call with Khalid Sheikh Mohammed. After his colleague fled the scene on foot, Nawar detonated the explosives. The truck detonated at the front of the synagogue, killing 14 German tourists, five Tunisians, and two French nationals. More than 30 others were wounded.

In June 2002, Sulaiman Abu Ghaith spoke on al-Jazeera to confirm that the attack was carried out by Nizar Nawar with al-Qaeda's help, since Nawar "could not see his Palestinian brothers killed while Jews walked freely in Djerba to enjoy themselves and practice their religion". The Boston Globe stated that his residence in Canada proved "that Canada, despite new antiterrorist measures approved by Parliament under intense pressure from the United States, remains an important haven for bin Laden's operatives"

In 2001, his father moved the remaining family members to France.

In 1999, Nizar Nawar told his family he was traveling to South Korea to work in restaurants. Nine months later he phoned his parents "very bitter, very angry", and explained he had no money and said the restaurant had refused to pay him. He asked them to help him fly back to Tunisia.

Nizar bin Muhammad Nasar Nawar (1978-2002), an alleged member of the Tunisian Combat Group, was accused of carrying out the 2002 Ghriba synagogue bombing, after planning its execution while living in Montreal, Canada.

Raised by his mother in Ben Gardane, Nizar Nawar was a "mediocre" student who never completed high school. His father, who moved to Lyon, France in 1971, visited the family routinely, but was unable to help his son gain an entry visa to France in 1999, since he could not prove he had the financial capacity to support him.
