Coastguard sailors who opened fire on a Taiwanese fisherman in Philippine waters were convicted Wednesday of his 2013 killing, which strained ties between the historically friendly neighbours. The eight Filipino crewmen said they had shot in self-defence after the fisherman’s vessel sailed directly at them in the seas just north of the main Philippine island of Luzon. “We are filing a notice of appeal so that what we perceived as errors of the trial court will be thrashed out,” Paul Jomar Alcudia, one of the lawyers of the officers, told AFP.
