BUENOS AIRES, Argentina — President Barack Obama is pledging that the United States will go after the Islamic State group aggressively and he says the world must be united against terrorism.

Obama says the U.S. will also providing any assistance it can to investigate the bombing attacks in Brussels.

Obama is speaking Wednesday about the Brussels attacks during a joint press conference with Argentine President Mauricio Macri. He’s visiting Argentina after spending three days in Cuba.
