Manila: Armed men torched a radio station owned by the Catholic Church in Occidental Mindoro, southern Luzon at one Wednesday morning, a TV report said.

No one was hurt but parts of the building that housed the dzVT radio station in San Jose City were damaged, regional police chief Superintendent Gregorio Olaguer said in a TV interview.

Suspects were not yet identified and no group has claimed responsibility for the attack, said Olaguer.

There were no evidences that could link the communist New Peoples Army (NPA) to the attack, said Olaguer.

The NPA, the armed wing of the 45-year old Communist Party of the Philippines (CPP) operate in southern Luzon, the base of its widely famous spokesman, Gregoro "Roger" Rosal.

Last October 10, the CPP belatedly announced that Rosal died of heart attack last June 22 this year.

There were attempts to set the same building on fire, said Olaguer, adding that authorities are using this lead in their investigation.

Other sources said the attack was meant to warn journalists.

Some 32 journalists were included in the massacre of 57 by a powerful political family in Maguindanao, southern Philippines in November 2009.

The influential Catholic Bishops Conference of the Philippines has not yet issued a statement on the incident.
