Beheading, like what the Islamic State (IS) has done to two American and two British hostages in the past few weeks, causes instant death to the victim. However, in a slower and more painful way of killing, the IS has prescribed death by stoning to a female adulteress.

The short video clip posted on Wednesday in YouTube and has so far got more than 2,000 hits, said the stoning involved a young Syrian woman stoned to death for committing adultery. Ironically, the leader of the mob than stoned her was the woman's own father.

The video showed clerics accusing her of adultery, while the woman asks for forgiveness from her father who tied a rope around her neck and told her to stop calling him "Father."

He brings her to a hole in the ground and orders the male crowd to begin the stoning, with the biggest stone reserved for the father to cast. The prayers of the veiled woman is heard, but her voice was eventually stilled.

The New York Times said the video was shot on Tuesday in the Syrian city of Hama. A bearded cleric is heard telling the adulteress to be content and happy over her death by stoning which "has been ordered by God."

The incident illustrates the persistent belief of many Middle Eastern nations of stoning adulterers by stoning, which is confirmed by the biblical account of a woman adulterer - often referred to as Mary Magdalene - who was saved from the mob by Jesus Christ who had said, "Let him who is without sin cast the first stone."

That scene is replicated in the 1988 film megged by Martin Scorsese in The Last Temptation of Christ.

Despite the notoriety of the IS for killing people, whether by decapitation or stoning, some young westerners continue to be drawn to the group.

On Tuesday, the FBI said that it stopped three girls from the Denver area in Germany on their way to join IS extremists in Syria. FBI spokeswoman Suzie Payne said the girls are safe and have been returned to their families in the US, the New York Post reports.

In April, FBI agents arrested 19-year-old Shannon Conley of Arvada, Colorado, as she tried to board a flight bound for Syria. Conley had trained with the US Army Explorers and wanted to use her skills in the jihad. Her siding with the IS appears to be the result of her relationship with a Tunisian man whom she met online and planned to marry.

Conley pleaded guilty in September to charges of conspiring to help Syrian militants and faces up to five years in federal prison and a $250,000 when she is sentenced in January.
