A local Philipppine politician was killed today when hooded gunmen opened fire on a convoy carrying about 50 people in another incident of election-linked violence. Police said the ambush in the Northern Province came barely a month after a massacre of 57 people in the southern province of Maguindanao. In today's assault, four hooded men shot at the convoy of 50 people carrying candidates and supporters of the opposition Nationalista Party after the group had left a Christmas party in the town of Dingras. Joen Caniete, who was running for a seat on the Dingras council in next year's national elections, was riddled with bullets and died immediately. Six other people traveling in the convoy, including two village officials and a police escort, were wounded.
