Trump called Colombia's president an "illegal drug leader" on Sunday and pledged to end U.S. aid to the South American country, following the leader's criticism of U.S. strikes on alleged drug boats in the Caribbean.

Mr. Trump accused Colombian President Gustavo Petro in a post on Truth Social of "encouraging the massive production of drugs, in big and small fields."

Hours earlier, Petro accused the U.S. in a series of X posts of hitting a fishing vessel in a strike it carried out last month, not a boat carrying drugs as it had claimed at the time. The Colombian leader said a fisherman had been killed in the attack, saying that in doing so the U.S. had "invaded national territory." He made a similar allegation earlier this month, claiming another boat that was struck by the U.S. military carried Colombian citizens — which the U.S. denied.
