MANILA, Philippines: Communist guerrillas killed three unarmed Philippine marines who were on their way to a market Sunday as a 22-day Christmas cease-fire began, military officials said.
Military officials condemned the attack on the marines, who they said were in civilian clothes, by about 20 New People's Army guerrillas near a farming village in the southwestern province of Palawan, about 360 kilometers (223 miles) south of Manila.
Troops had been ordered to hunt down the attackers, the military officials said.
"This is an inhuman act," Lt. Col. Jacinto de Vera, spokesman for the military's Western Command in Palawan, told ABS-CBN TV network.
De Vera said the three marines, who were riding in a jeep when attacked, were not carrying firearms in observance of a Christmas-season cease-fire that the government had unilaterally imposed and that began early Sunday.
They had planned to get food at a village market, stop at a church to pray and then pick up construction materials elsewhere to repair their rural outpost, de Vera said.
A military hunt for the attackers would not violate the Dec. 16-Jan. 6 cease-fire, which allows government troops to defensively respond to rebel attacks, he said.
The rebels did not immediately issue a public reaction to the military's accusations.
