There are no smiles in pictures of President Obama and Russian President Vladimir Putin as they met on the sidelines of the United Nations General Assembly in New York City.

Their meeting came amid a disagreement over Russia's support for Syria in its fight against ISIS. Over the weekend, Iraq announced an agreement in which Iraq, Russia, Iran and Syria would share intelligence to counter the terrorist group.

In his speech at the United Nations, Putin said it would be a mistake to refuse to cooperate with the Syrian government.

Obama said the U.S. would work with any country to fight ISIS, but not if the goal is to return Syria to the status quo. (Metro Networks Inc.)
