Eighteen people were killed and 26 wounded in a suicide bombing at the Cherchell military academy west of Algiers, the defence ministry said on Saturday revising its own toll given hours earlier. The ministry said 16 officers and two civilians were among the dead. Twenty wounded had been discharged but six people were still in hospital, one in critical condition. The wounded were evacuated to hospitals in the nearby towns of Sidi Ghiles and Tipaza, as well as to the army's central Ain-Naadja hospital in Algiers. The ministry had earlier revised a toll given Friday by hospital officials of 18 dead and dozens of wounded, saying 11 people died.
