The United States has indications other countries are willing to launch air strikes against ISIL militants in Syria, its U.N. ambassador said on Sunday, predicting "we will not do the air strikes alone."

Washington is trying to build an international military, political and financial coalition to defeat the ISIL group that has seized swathes of Iraq and Syria.

U.S. Ambassador to the United Nations Samantha Power was asked on CBS' "Face the Nation" if Washington had any indication other countries were willing to launch air strikes in Syria.

"We do," Power said. "But we're going to leave it to other nations to announce for themselves what their specific commitments to the coalition are going to be."

Power highlighted U.S. efforts to build a coalition against ISIL on television news shows as world leaders gathered in New York for this week's U.N. General Assembly.

The United States has launched air strikes against ISIL within Iraq and President Barack Obama on Sept. 10 authorized air strikes in Syria aimed at denying ISIL fighters safe havens in either country.

Power refused to identify any of the countries that might join any air strike effort in Syria, but told CBS, "we do indeed have the support along the lines that I've described."

"There's universal support, I think, for degrading and destroying this group," Power said on ABC's "This Week."

"I will make you a prediction ... which is that we will not do the air strikes alone if the president decides to do the air strikes," she said.

France last week launched its first air strikes inside Iraq, but its president, Francois Hollande, has ruled out strikes inside Syria as well as sending in ground troops.

The United States, president of the U.N. Security Council for September, called a meeting on Iraq on Friday where Secretary of State John Kerry said every nation, including Iran, had a role to play in the coalition.

Obama, who said last week 40 countries had pledged to help, has already ordered 1,600 U.S. troops into Iraq.

The U.S. president will give a speech at the General Assembly on Wednesday to make the case again for world action against ISIL.
