The first encounter erupted in Sitio Kansoman, Barangay San Juan in Bayugan, Agusan del Sur last Tuesday when patrolling members of the Armys 29th Infantry Battalion encountered at least 15 guerrillas.
Last Thursday morning, soldiers and rebels clashed anew in Marihatag, Surigao del Sur. A certain S/Sgt. Malaga was wounded.
But Maria Malaya, NPA spokeswoman in the Caraga region, claimed otherwise in a radio interview, saying the military suffered casualties.
Malaya accused the military of violating the government-declared ceasefire by infiltrating rebel-influenced areas.
She said the NPA was still thinking of reciprocating the Christmas truce.
The NPA, the military arm of the Communist Party of the Philippines, is marking its anniversary on Dec. 26.
Last Dec. 4, NPA rebels burned at least four units of heavy equipment of construction firm Concepcion Basic Builders Inc. in Barangay San Roque in Bislig City, Surigao del Sur.
They admitted that they torched a bulldozer, grader, roadroller and bucket bulldozer due to the companys refusal to pay "revolutionary taxes."
