WASHINGTON — President Obama again vowed Friday to help Iraq's government fight insurgents who are closing in on Baghdad, while a senior defense official told USA TODAY that American air power options are currently limited.
"The United States will do its part," Obama told reporters at the White House, but added that ultimately it is up to the Iraqis themselves to "solve their problems" and "we are not going to be able to do it for them."
Obama also said: "We will not be sending U.S. troops back into combat in Iraq."

A senior defense official said U.S. air power options in Iraq are limited because the closest aircraft that could wage a bombing campaign against Islamist militants who have captured several of the nation's largest cities are at least 800 miles away.
The insurgents — the Islamic State of Iraq and Levant (ISIL), an al-Qaeda splinter group — started their offensive Monday. They are trying to create an Islamic territory including Iraq and Syria. They have taken Mosul, Iraq's second-largest city, and Tikrit, the birthplace of former Iraqi dictator Saddam Hussein.
To be effective, air strikes would require the Iraqi army to step forward and engage insurgent forces on the ground, said the official, who spoke on the condition of anonymity because the details of potential air power options are not authorized to be released publicly.
In any event, U.S. warplanes are not based close enough at the moment to conduct such a campaign, he said.
"We have basically left Iraq," the official said.
Obama, who was on his way to appearances in North Dakota and California over the next two ways," said the planning for any type of American action "is going to take several days, and "won't happen overnight."
The insurgents are about 100 miles from the Iraqi capital of Baghdad. The Iraqi military under Prime Minister Nouri al-Maliki has so far been unable to stop them.
At the White House, Obama said Iraq's government has been unable to deal with the "terrorist offensive," and he has conferred with his national security team about possible short-term military action.
The ISIL obviously poses a danger to Iraq, "it could pose a threat, eventually, to American interests," Obama said.
Obama also said that Iraq's government needs to deal with the sectarian divisions that have given risen to the violence. He also noted signs that civil war in Syria has spilled over into neighboring Iraq.
"This is a regional problem and it is going to be a long term problem," Obama said.
Despite the limitations, Secretary of State John Kerry said Friday that President Obama will act quickly.
"Given the gravity of the situation, I would anticipate timely decisions from the president regarding the challenge ... I am confident the US will move rapidly and effectively to join with our allies in dealing with this challenge," Kerry said in London.
White House officials said they are assessing their options, both militarily and legally.
Obama "is considering all options in response to the question about potential direct action by the United States military," said White House spokesman Jay Carney. "But we would have to get back to you on how that would proceed if that decision were made."
U.S. air power options in Iraq are limited now, because the closest aircraft that could wage a bombing campaign against Islamist militants who have captured several of the nation's largest cities are at least 800 miles away, a top defense official told USA TODAY Friday.
