OTTAWA (AFP) - Twelve Algerian employees of the Canadian engineering firm SNC-Lavalin were killed and 15 others were wounded in a car bombing Wednesday in Algeria, the company announced. The SNC-Lavalin staff were travelling to work on the Koudiat Acerdoune water treatment plant and distribution project when their bus was attacked, the company said. Earlier, two fresh car bomb attacks in eastern Algerian town of Bouira killed at least 11 people and injured 30 others, Algerian state radio reported earlier Wednesday, with the country still in shock from a suicide bomber who killed 53 people a day earlier. Bouira is part of a so-called "zone of death" it forms with Algiers, Tizi Ouzou and Boumerdes where attacks have been rife.
