At least seven people were wounded, some badly, when an explosion rocked a lawmaker's house in the northern Philippines in what may have been an accident or an attack by a political rival, police said Wednesday.
Three sons of House Rep. Cecille Luna were among those wounded in the blast in Luna's home in Abra province's capital, Bangued, late Tuesday as the family gathered for the Christmas Day holiday, said police Senior Superintendent Alexander Pumecha.
One of the sons and two other victims who suffered second- and third-degree burns were hospitalized in Manila, Pumecha said. All the injured were in stable condition.
Pumecha, Abra's police chief, said investigators have not determined what caused the blast.
"It might be politics," he said, adding it was also possible that firecrackers accidentally exploded.
Luna won a tightly contested race against then-Gov. Vicente Valera, whose family has been in power in the province for three decades. Warlords with private armies are known to operate there, and the local politics have a history of violence.
Earlier Tuesday, Mayor Ceasar Balacanao Rafael of Paracelis town in nearby Mountain Province was shot dead by unidentified men armed with M16 rifles, police Senior Superintendent Joseph Adnol said. The gunmen ambushed his car as he was on his way home from visiting his farm, he said.
Adnol said investigators were considering politics, a personal grudge or revenge as possible motives.
