U.S. diplomats on Sunday said some Arab nations have signified their intent to join the fight against the Islamic State of Iraq and Syria (ISIS, also known as ISIL).

Although largely unidentified, "several" Arab nations have reportedly offered to contribute air power to the United States, Britain and other countries as it aimed to eradicate the ISIS and its terror threat to the world.

The supposed air power do not necessarily mean dropping bombs, State Department officials who are with Secretary of State John Kerry, now in Paris, said.

The interested Arab nations could, among others, fly arms to Iraqi or Kurdish forces, stage reconnaissance flights or deliver logistical support and refueling, they said.

Secretary of State John Kerry also even said there were others which have offered to "put troops on the ground."

The New York Times quoted a State Department official as saying that the decision as to how the work will be distributed and carried out among the participants would come from the Iraqis. "It has to be well structured and organized."

For one, Iraq's new Shiite-led government will be the one to approve all airstrikes against ISIS in Iraq, something that could prove delicate with Saudi Arabia and the United Arab Emirates which have Sunni Arab governments.

"We have to sort through all of that because you can't just go and bomb something," the State Department official.

What's most definite, though, is that we don't want this to look like an American war, the official said.

"Originally this is not a war," Kerry said on CBS's 'Face the Nation.' "This is not combat troops on the ground. It's not hundreds of thousands of people."

Kerry is expected to announce which Arab nations have joined the west's fight against the ISIS early this week.

U.S. President Barack Obama on Wednesday announced expanding the U.S. airstrikes against the ISIS in Syria and Iraq.
