(CNN) -- In two audiotaped messages broadcast Saturday, a man purporting to be Osama bin Laden discussed Iraq and threatened to launch suicide attacks against the United States and any countries that help it.

According to a CNN translation of the messages aired by the Arabic-language news network Al-Jazeera -- one addressed to Iraqis and Arab Muslims throughout the world, the other to the American people -- feature a man claiming to be the al Qaeda leader discussing suicide attacks against U.S. troops in Iraq and against the Iraqi Governing Council.

He also gave specific figures for the U.S. economy, saying the country is facing a deficit of more than $450 billion. The United States announced an expected $455 billion budget deficit in the current fiscal year July 15.

The voice also referred to Mahmoud Abbas as though he were still Palestinian prime minister. Abbas resigned the post September 6.

CIA spokesman Mark Mansfield said officials are "doing a technical analysis" of the tapes that has "not yet been completed." CIA analysts generally state within two days whether they believe voices on tape are who they say they are.

CNN cannot independently confirm whether the voice is bin Laden's.

White House spokesman Scott McClellan told CNN: "It is a reminder the global war on terrorism continues and the enemy has no regard for innocent life."

Last month, Al-Jazeera broadcast an audio message that the CIA later said was most likely in bin Laden's voice. The broadcast included video of him and another al Qaeda leader walking in a mountainous area.

The most recent message to Americans threatened suicide attacks against U.S. citizens in and outside the United States. It called on Americans to reject President Bush's "aggression" against Iraq, which he called part of a Jewish plot "against our religion and our people.

"Most of you are a mob with no trace of good morals," he said, addressing Americans. "We will continue to fight you as long as we have weapons in our hands."

The Department of Homeland Security, in a statement, said the tapes simply emphasize that the United States remains al Qaeda's first target.

Tape says U.S. is on "a crusader's war"

The message continued with threats to U.S. allies.

"Let the transgressors know that we reserve our right in responding when and where we see appropriate against all the countries that participate in this unjust war [in Iraq] -- especially Britain, Spain, Australia, Poland, Japan and Italy," he said. "Not to be excluded those Muslim countries that participate, especially the countries of the [Persian] Gulf and Kuwait."

In the second message, directed to Iraqis and Arab Muslims worldwide, he called the U.S.-led effort in Iraq "a crusader's war" and issued a rallying cry for Muslims to launch "jihad" operations against the United States and its allies.

"The Romans have gathered under the banner of the cross to fight the nation of the prophet Muhammad -- so take up jihad," he said.

"You have no reward but in jihad," he added, calling those who support the United States "infidels and heretics.

"Know that this war is a new crusading campaign against the Islamic world, and this is a very critical war to the nation as a whole, because it has dangerous ramifications and consequences impacting Islam and its people -- to an extent that Allah only knows."

He also called on Muslims to fight those in their midst who support the building of a democratic, representative government in Iraq.

"There have been new voices, similar to those before them in Palestine, Egypt, Jordan and Yemen, that are calling for a democratic and peaceful solution to the problem of dealing with infidel governments, or dealing with invaders whether they are Jews or Christians -- and that is as an alternative to fighting in the way of Allah. Therefore it is imperative, that we briefly warn you against the danger of this deviant methodology, which is in violation of the way of Allah."

He accused Afghan President Hamid Karzai and Abbas of operating treasonous "puppet governments ... set up to sabotage jihad."

Calling on Muslims to continue "martyrdom" operations against "infidels and crusaders," he said, "to my mujahedeen brothers in Iraq ... only Allah knows that if I had found a way to your battlefield, I would not stay behind."
