SAN JOSE, Costa Rica (AP) — President Barack Obama says the United States will keep pressure on Syria while investigating whether the government has used chemical weapons against its people, but that it must proceed carefully.
Asked about Syria at a news conference in Costa Rica, Obama said: "We will stay on this."
He says if systematic use of chemical weapons in Syria is confirmed, the United States will present that evidence to the international community, because it concerns the entire world.
But Obama declined to say what action the U.S. might take. He called for caution to avoid unintended consequences. In his words, "It's important for us to do it right."
