Officials say five police officers, including a town police chief, were killed in an attack by suspected communist rebels in the northern Philippines.

Chief Superintendent Francisco Villaroman said Monday that two officers were also wounded in the ambush late Sunday in Cagayan province, 360 kilometers north of Manila.

Villaroman said the police vehicle was first hit by at least one explosion and that suspected New People's Army rebels then opened fire on the car.  

The attack took place days after communist and government negotiators agreed to resume peace negotiations in February in Norway.

Peace talks broke off in 2004, when the rebels accused the government of instigating the inclusion of the Communist Party and its armed wing, the NPA, on U.S. and European lists of terrorist organizations.
