The death toll from the powerful motorcycle bomb blast Tuesday afternoon in the restive southern Philippines has risen to two, while eight others were wounded, officials said. A homemade bomb fashioned from four 81-milimeter mortar shells exploded in front of a gun shop around 2:15 p.m. along Quezon Avenue in the southern Philippine city of Cotabato, leaving two people dead, said administrator Atty. Cynthia Guiani Sayadi. The blast left one dead on the spot while another passed away in hospital. The wounded were eight other civilians. Lt. Col. Prudensio Asto, a regional military spokesman, told reporters a motorcycle packed with a homemade bomb exploded at CWAT gun store. The bomb had a mobile phone that served as the triggering device.
