An online al Qaeda magazine is calling for jihadis to damage the US economy by killing business leaders and entrepreneurs, according to analysts.
An article in Inspire, which was published on Saturday, calls for "Professional Assassinations" and features the image of a hooded man watching a home from the outside.
It also includes a photo montage showing Microsoft founder Bill Gates, a gun and a blood spatter, the Washington Times reported.
The Middle East Media Research Institute (MEMRI), which obtained a copy of the magazine, said it provides detailed information on preparing for and carrying out targeted assassinations.
It quotes Inspire editor Yahya Ibrahim as saying : "The prophet ordered the killing of many criminal leaders using this method... and here we are, following the footsteps of the prophet on how he dealt with his enemies and friends".
He adds: "We will never put down our weapons until we fulfil what Allah wants from us.
