Algiers - Algerian Islamist rebels slit the throats of a family of seven and booby-trapped the corpse of a seven-month-old baby which wounded a government soldier when it exploded, a local newspaper reported yesterday. The Sawt al Ahrar daily said the Islamist guerrillas had murdered the infant, his parents and four sisters and brothers in the attack on Monday night at Tizi in the western province of Mascara, 300 km from Algiers.
