ST. PETERSBURG, Russia - President Barack Obama says he had a "candid and constructive conversation" with Russian President Vladimir Putin on Syria.
>The White House says the President will address the nation Tuesday evening on the Crisis in Syria.

Putin told reporters they spoke for 20 or 30 minutes Friday and focused on Syria. The Russian president says while they disagreed, the meeting was constructive.
Obama says the humanitarian situation in Syria and along its borders is "only getting worse" and stresses that the problem is "not in anyone's interest."
