US must do something to stop Al-Queda with the help of the world. It is totally bizarre tactics of having local cells kidnap and behead Americans and put it on Internet to show the world the level of barbaric behavior.

Beheadings like that of American hostage Paul M. Johnson Jr. in Saudi Arabia add a new layer of horror to militant attacks, and al Qaeda-linked groups have turned to the tactic to drive away Westerners -- and bring glory to themselves among supporters.

And it's simple to carry out. A victim is snatched, shown bound and menaced by masked gunmen, then days later is killed and beheaded.

The bloody images are videotaped, photographed and posted on the Internet.
What began as a gruesome form of bloodshed in war zones like Kashmir, Chechnya and the southern Philippines has moved to the Middle East, with at least two Americans decapitated in just over a month in Iraq and Saudi Arabia.

"It's a political, psychological ploy to show the enemy is merciless, vengeful and will stop at nothing," Richard Murphy, a former U.S. ambassador to Saudi Arabia, told The Associated Press. Militants know "what will cause maximum shock in the Western public and particularly the American public."

Johnson was killed Friday, nearly a week after he was abducted in the Saudi capital, Riyadh. Photos of his bloodied, severed head appeared on a Web forum used by Islamic radicals.

The photos come on the heels of other graphic images, such as the videotaped last moments of Nicholas Berg, kidnapped in Iraq and decapitated in front of the camera in early May.

Another video showed American Robert Jacobs being shot to death outside his Riyadh home June 8. His killers then kneel over his body, their backs to the camera, and appear to cut off his head -- though the decapitation is not seen and was never confirmed.

The first beheading touted by Islamic militants was that of Wall Street Journal reporter Daniel Pearl, slain in Pakistan in 2002.

The latest beheadings have occurred in the two countries where Americans and other Westerners have the greatest presence in the Middle East.

"Beheadings are done to try to show that no Westerners are safe," Rachel Bronson, the Director of Middle East Studies at the Council on Foreign Relations. "It has a chilling effect on Westerners in Saudi Arabia."

The Saudi government executes murderers, drug dealers and other criminals by beheading under its strict interpretation of Islamic Sharia law.

Decapitation rarely occurred in past militant attacks in the Middle East, where terror tactics have included hijackings, suicide bombings or gun attacks. Hostages were often taken and killed in Lebanon's civil war, but victims were rarely if ever beheaded.

Al Qaeda militants may be using the technique to misleadingly give the killings an Islamic veneer, Murphy said.

"It's not (Islamic)," he said. "To have a Quranic capital punishment, you have to have a legal procedure with strict standards."

Instead, the practice may find its roots in more distant, brutal battlefields. The long civil war in Algeria, the war in Chechnya and the anti-India insurgency in Kashmir have all seen beheadings of local residents or troops. Foreign fighters in Bosnia also were accused of at least one beheading during the Balkan wars of the 1990s.

Westerners caught in those conflicts also fell victim. In 1998, three Britons and a New Zealander were abducted and beheaded by Chechen militants.

In May 2001, members of the al Qaeda-linked Abu Sayyaf group in the Philippines kidnapped 17 Filipinos and three Americans and decapitated several of the hostages, including American Guillermo Sobero.

Radicals from all those conflicts have been involved in al Qaeda cells or groups linked to Osama bin Laden's terror network.

But Pearl's killing brought the use of decapitation most directly into the al Qaeda network. Some U.S. officials have said they believe al Qaeda's No. 3 figure, Khaled Sheikh Mohammed, now in U.S. detention, may have been involved in the killing.
