COTABATO CITY—A powerful homemade bomb exploded in a compound housing offices of the Autonomous Region in Muslim Mindanao in this city, wounding one person, police said Saturday.
The blast on Friday came two days before Latin American ambassadors were scheduled to visit the city to scout for investment opportunities, officials said.
City police chief Ajijul Taradji said the bomb was apparently planted in a jeep that entered the compound of the ARMM.
The explosion destroyed the jeep and wounded a local trader who sustained shrapnel wounds but was in a stable condition, Ajijul said.
The explosion was the second to rock Cotabato City this week. On Wednesday unidentified men tossed a hand grenade into a residential district, killing an eight-year-old child and wounding three.
Police said no motive for either attack had been established and no group had claimed responsibility.
Heavily armed police have been deployed in the ARMM compound.
The ARMM consists of four mostly Muslim provinces and a city in the southern island of Mindanao, the scene of a decades-old Muslim separatist rebellion.
The Moro Islamic Liberation Front rebels operate in the area, as do other armed groups of former guerrillas who have turned to banditry.
