Two bombs ripped through adjacent shopping centers in the southern Philippine city of Zamboanga today, killing at least five and wounding more than 140 others. Police defused seven other explosive devices planted around the commercial area. The military labeled the attack a terrorist act and blamed the Abu Sayyaf Muslim rebel group. The attack came just hours after Lieutenant General Abaya assumed his post as top commander in the south and vowed to crush Muslim Abu Sayyaf guerrillas operating in nearby Basilan and Jolo islands. Police said 16 people were detained after today’s attacks.
