An improvised bomb exploded Tuesday in front of a gun store in the restive southern Philippines, killing at least one person and wounding nine others, including a 7-year-old girl.
No one has claimed responsibility for the attack in southern Cotabato city, where Muslim separatist rebels and criminal gangs are active. Police said they were looking into a possible land dispute.
The bomb was placed inside a motorcycle in front of the store and remotely detonated using a cellphone, said police Superintendent Roberto Badian.
A security guard on his way to work was killed while shrapnel and glass splinters from the shattered window hit nine other people up to 33 feet (10 meters) away, said Badian, the city police chief.
Police have no suspects yet but are looking into reports that the owner of the gun store was involved in a land dispute, said police regional operations chief Felicisimo Khu Jr.
Cotabato City Administrator Cynthia Guiani Sayadi called the bombing "barbaric and un-Islamic" and noted it occurred during the Muslim holy month of Ramadan.
The blast also damaged four vehicles and the windows on nearby stores.
The predominantly Muslim region has been hit by bomb attacks blamed on militants and extortionists.
