ST. PETERSBURG, Russia (AP) President Barack Obama says he's encouraged by the discussions he's had with world leaders about the situation in Syria.
He says there is a growing recognition that the world "cannot stand idly by" after a deadly chemical weapons attack he says was carried out by the regime in Syria.
Obama says leaders from Europe, Asia and the Middle East agree with him that international norms against the use of chemical weapons must be upheld.
Obama spoke at a news conference Friday in St. Petersburg, Russia, at the close of an international economic summit.
