On 15 May 1988, the Acropole was shocked by tragedy, when a terrorist commando of the Abu Nidal group bombed the restaurant, killing a British couple with their two children, another Briton, and two Sudanese workers,[10] leaving 21 people injured.[11][12] According to The Economist, the attack on the soft target, which was well known for hosting many Westerners, was "in apparent revenge for the Israeli assassination in Tunisia of the PLO military leader Khalil al-Wazir."[13] Five members of the group were arrested and convicted. Their death-sentences were turned into prison-time, when the relatives of the Sudanese victims agreed to the payment of "blood money". In January 1991, shortly before the Gulf War started, the new regime of the Islamist leader Hassan Al Turabi released the five.[14]
