President Donald Trump has escalated his campaign against drug-smuggling vessels in Latin America, following a controversial strike near Venezuelan waters that killed a Colombian fisherman. The Colombian government disputes Washington's claim that the fisherman was a drug trafficker, intensifying tensions between the two countries. Trump responded by threatening to cut off counter-narcotics aid to Colombia and expand military strikes, while U.S. officials maintain that their intelligence is conclusive but have not released detailed evidence. The strikes, which have killed more than 30 people, have prompted calls from Congress for greater transparency and legal justification.
