And guerrilla leaders may be robbing banks to replenish their dwindling money supply, officials said.

Gen. John Abizaid (search), chief of the U.S. Central Command (search), told Fox News' Bret Baier -- who is traveling with Gen. Richard Myers, chairman of the Joint Chiefs of Staff, in Iraq -- that U.S. forces are initiating new raids against the opposition every day and are starting to understand the structure of terrorist cells in Iraq.

Forces believe the network was developed by Iraqi intelligence before the war.

"We continue to take it down," Abizaid said of the resistance.

Abizaid said an additional nine targets were captured in Samarra recently -- in addition to the over 73 that were rounded up on Tuesday, including a suspected local Fedayeen (search) leader, Qais Hattam (search). It is believed they constituted a whole cell.

The U.S. military said those captured were holding a meeting, apparently to plan future attacks.

Abizaid said he thinks financing for the resistance cells is drying up and that could be why Iraq is seeing an upsurge in bank robberies lately.

"You notice in the country there have been several interesting attempts to rob banks lately," Abizaid told Fox News. "I don't want to jump to conclusions but I believe money is starting to dry up in the resistance, because we are starting to understand where the money is coming from, not only internally but externally."

Some of the new information U.S. forces are acting on came from a briefcase found on Saddam when U.S. troops took him into custody over the weekend. Abizaid said it's like pulling on a string -- one part leads to another, and U.S. forces are rounding up more guerrilla fighters and former regime members every day.

It's believed that there are eight cells still operating Baghdad and a few thousand enemy fighters remaining, but only a few hundred hardcore fighters left.

'Operation Ivy Blizzard'

In Wednesday's raid in Samarra, dubbed Operation Ivy Blizzard, the 4th Infantry Division and Iraqi forces detained at least a dozen people in that area, which in recent weeks has emerged as center of anti-U.S. attacks in the so-called "Sunni Triangle" north and west of the capital.

"Samarra has been a little bit of a thorn in our side," said U.S. Army Col. Nate Sassanan. "It hasn't come along as quickly as other cities in the rebuilding of Iraq. This operation is designed to bring them up to speed."

Sassanan's deputy, Capt. Matthew Cunningham, said Samarra has a core of about 1,500 fighters.

Saddam Still in Baghdad

Meanwhile, the U.S. military is holding Saddam in the Baghdad area, a member of the Iraqi Governing (search) Council said Wednesday.

"He is still in greater Baghdad," said council member Mouwafak al-Rubaie. "Maybe he will stay there until he stands trial."

Al-Rubaie spoke at a news conference where council members issued a statement asking for Iraqis to seek reconciliation following the weekend capture of Saddam.

U.S. officials have confirmed that the former dictator was at an undisclosed location in Iraq.

The CIA, which was put in charge of interrogating Saddam by Defense Secretary Donald Rumsfeld, is showing the deposed leader videotapes of rallies against him, of prisoners being tortured and executed under his regime and of the unearthing of mass graves his regime created.

The goal is to provoke him into making unguarded statements by confronting him with evidence that could be used in a war-crimes trial, two officials receiving reports on the interrogation -- one in the administration and one in an intelligence agency -- told USA Today.

Sen. John McCain, R-Ariz., said whether Saddam talks or not, he shouldn't be allowed to negotiate for leniency.

"The magnitude of the crimes that this despot, this despicable character, has committed warrant the ultimate penalty in my view, and to give him anything less in exchange for information would not be appropriate," McCain said in a television interview Wednesday.

The 'Ultimate Penalty'

And on the question of whether or not Saddam should get the death penalty for the myriad of crimes he has committed, President Bush said the former dictator deserves the "ultimate penalty."

But that sentiment is facing objections from European countries, the United Nations and the Vatican, which are adamantly opposed to capital punishment.

"Let's just see what penalty he gets, but I think he ought to receive the ultimate penalty ... for what he has done to his people," Bush said Tuesday in a television interview. "I mean, he is a torturer, a murderer, they had rape rooms. This is a disgusting tyrant who deserves justice, the ultimate justice."

Bush said Saddam's punishment "will be decided not by the president of the United States but by the citizens of Iraq in one form or another."

Former New York City mayor and prosecutor Rudy Giuliani told Fox News that "there's no question" the trial should be in Iraq, since "the primary crimes that he committed were against the Iraq people."

"I think from the point of view of justice and history, there should be a full explanation and expedition of crimes he committed against the Iraqi people," Giuliani added. "The sum of his crimes were really unbelievable and his contribution to world terrorism" is great.

Many American lawmakers, while stressing that it's up to the Iraqi people to decide Saddam's fate, are all for the Butcher of Baghdad to be sentenced to death.

"I don't think it's up to us to tell them what his sentence should be," Rep. Lincoln Diaz-Balart, R-Fla., told Fox News, but they should give him "whatever sentence is appropriate … including the death penalty."

Added Rep. Martin Frost, D-Texas, who will join a delegation on a trip to Iraq on Friday: "I think the death penalty ought to be an option."

Asked whether killing Saddam will make him a martyr, Frost replied: " I think its up to the Iraqi people to make that decision ... [but] I think what he did is so serious that he ought to get the death penalty."

The Iraqi Governing Council has established a war crimes tribunal and hopes to put him on trial for human rights abuses. Council member Adnan Pachachi said "all stages of the trial will be public."

The documents found with Saddam may reveal the degree to which he was involved in directing or financing the resistance -- information that could affect his trial.

"It is conceivable, to the extent he was involved in the post-major combat operation terrorist activity that's taken place in that country, that that could affect charges brought against him," Rumsfeld told reporters at the Pentagon on Tuesday.
