ATLANTA (CNN) -- As more than one billion Muslims prepare to celebrate Ramadan, terror experts are mixed about whether the holy month is a tool for recruiting terrorists.

Some terrorism experts and Islamic scholars say Ramadan gives extremists an opportunity to enlist new recruits.

"It's a time which can be exploited by radical clerics to motivate individuals into taking action on the basis they are somehow serving their religion," says terror expert M.J. Gohel.

And analysts see another temptation for terrorists: exploiting the Battle of Badr, a symbolic date in Muslim history, which falls near the U.S. presidential election.

This September 11 marks the third unforgettable anniversary of the worst mass murder in American history.

After September 11, many in the Muslim world chose denial and hallucination rather than face up to the sad fact that Muslims perpetrated the 9-11 terrorist acts and that we have an enormous problem with extremism and support for terrorism. Many Muslims, including religious leaders, and "intellectuals" blamed 9-11 on a Jewish conspiracy and went as far as fabricating a tale that 4000 Jews did not show up for work in the World Trade Center on 9-11. Yet others blamed 9-11 on an American right wing conspiracy or the U.S. Government which allegedly wanted an excuse to invade Iraq and "steal" Iraqi oil.

With the nation on high alert for al-Qaida terrorists, the Department of Homeland Security is putting its border officers through "etiquette" classes to soften their image and make them less threatening to arriving foreign immigrants, WorldNetDaily has learned.

NEW YORK - Police searched trucks, blocked streets and posted machine-gun toting officers outside financial landmarks Monday, a day after the government's chilling warning that terrorists might target the buildings with bombs.

(CNN) -- Australia and Italy have received warnings through a statement purportedly from militants linked to al Qaeda that demanded those countries withdraw troops from Iraq.

The message was posted on an Islamist Web site Saturday and was signed by a group identifying itself as Islamic Unification (Islamic Tawhid), an al Qaeda-linked organization in Europe.

A mysterious power failure at Logan Airport that delayed dozens of flights for more than five hours has still not been explained – six days later.

Airport officials insist airline security was not compromised during the blackout Monday at Logan International's Terminal E, but backup electrical systems failed to kick in as they are programmed under such circumstances.

Logan is the airport from which two of the Sept. 11 hijacked planes originated.

Iran apprehended British military personnel and Navy vessels earlier this week in order to secure release of 40 "suicide operations volunteers" held by the UK, according to an Iranian Revolutionary Guard source.

The source told the London Arabic-language daily Al-Sharq Al-Awsat that the British Army command in Iraq received the demand from the Revolutionary Guard, reported the Middle East Media Research Institute.

According to the source, the content of the message was very simple: "Release our comrades, whom you are holding, and we will release your soldiers."

KHOBAR, Saudi Arabia - Tens of American, European and other hostages were released Sunday and a gunman believed to be the lead Islamic militant holding them was arrested, a Saudi security official said, adding that two other gunmen were "in the process of being arrested."

Two Chinese diplomats, away from their Los Angeles consulate improperly, recently sped their vehicle past a Los Alamos National Laboratory guard post near classified facilities in what U.S. officials think was an intelligence mission, The Washington Times has learned.

The diplomats, identified as Hua Yu and Bo Lai, were on an intelligence-gathering mission that is raising new worries of Chinese nuclear spying against the United States, according to U.S. officials familiar with the incident.

The top U.S. official in Iraq says Wednesday's gruesome attacks on four American civilians whose burned bodies were put on display in the town of Fallujah will not go unpunished.

"It's going to be deliberate, it will be precise and it will be overwhelming," U.S. General Mark Kimmitt said, speaking to reporters in Baghdad. He warned insurgents in the town of Fallujah to be prepared for U.S. forces to strike back following Wednesday's killing of four American contractors by a frenzied mob that dragged their charred bodies through the streets.

Televised footage of the act has provoked outrage from Americans in the United States and led U.S. administrator in Baghdad Paul Bremer to issue a warning.

WASHINGTON (CNN) -- This week's deadly train bombings in Spain will not lead to a rise in the U.S. color-coded terror threat alert system, a Department of Homeland Security spokesman said Friday.

"Based on the current intelligence, we have no specific indicators that terrorist groups are considering such an attack in the U.S. in the near term," said department spokesman Brian Roehrkasse.
