The son of Abdullah Azzam, Osama Bin Laden's spiritual mentor, has described the string of terror attacks that have swept Egypt, Britain and other countries lately, as a crime.

He said those terror groups using his father's name were only doing so to market their operations.

"If Abdullah Azzam were alive, he would have been the first fighter against that ideology," Hudhaifa Abdullah Azzam said in an interview with Al Arabiya network broadcast late Tuesday.

"I won't use the term terrorism, because it is an American and European terminology, but we can call it criminality, the bloodshed of innocents, aggression on those whom God has ordered their blood be preserved," Azzam said.

Abdullah Azzam was a Palestinian who led militants in Afghanistan and was killed there in 1989 by a roadside bomb. He was once considered the spiritual mentor of Al Qaida chief Osama Bin Laden.

Abdullah Azzam studied Islamic theology in Egypt before travelling to Saudi Arabia where he lectured in Islamic law.
