Philippine officials say two Americans were among 19 suspected communist guerrillas, who were killed in clashes with Filipino troops in a central province a week ago. The National Task Force to End Local Communist Armed Conflict said Saturday night that the Americans were killed with 17 other New People’s Army guerrillas in a series of clashes with troops on April 19 in Toboso town in Negros Occidental province. The task force warned Americans of Filipino descent in the United States to be wary of being lured by left-wing activist groups into supporting Filipino insurgents in the Philippines in a recruitment process it described as “terror-grooming.” The deadly fighting was first reported on Monday.
