BEIRUT (AFP) – Two people were killed when a bomb ripped through a shopping center in a Christian area north of Beirut, the second explosion since the assassination last month of ex-premier Rafiq Hariri plunged Lebanon into political turmoil. Police confirmed that the blast, which occurred near the port of Jounieh 20 kilometers (12 miles) north of Beirut was caused by an explosive device. The dead were two foreigners, whose identity has yet to be confirmed, while three were wounded, police said Wednesday. The blast followed an explosion in another Christian district early Saturday, which injured 11 people, and seemed certain to heighten fears of a resurgence in the sectarian violence that devastated Lebanon during its 1975-1990 civil war.
