Thomas Dietrich

Osama and Salem bin Laden purchase anti-aircraft missiles for Arab volunteers fighting in Afghanistan in a deal concluded at the Dorchester Hotel in London. The transaction results from a request by Osama that Salem help him with two purchases, of the anti-aircraft missiles and of equipment to refill ammunition shells for AK-47 assault rifles.
Middleman – Salem attempted to obtain the missiles from the Pentagon, but was rebuffed (see (Early-Mid 1986)), and brought a German acquaintance named Thomas Dietrich in to help him complete the deal. It is difficult to arrange as, even though the bin Ladens are backed by the Saudi government, they do not have clearance to buy the missiles from Western authorities. Dietrich has contacts at the arms manufacturer Heckler & Koch and also gets an arms salesman to meet Salem and Osama in Dubai, United Arab Emirates. However, the salesman tells Osama that refilling the ammunition makes no sense and it would be simpler to just purchase it on the international market. For the missiles, Osama, Salem, Dietrich and Dietrich’s contacts meet two or three times at the Dorchester Hotel over a period of six to eight weeks. Dietrich will later learn that his contacts help arrange the purchase of Soviet SA-7 missiles in South America, as well as the ammunition.
Paid in Oil – However, there is a problem with the deal because the bin Ladens want to pay for the weapons not with cash, but with oil, “just a tanker offshore,” according to Dietrich. This causes trouble as “a company like Heckler & Koch, they don’t want oil, they want money.” Dietrich is not aware of the source of funding for the purchases, but author Steve Coll will note, “The best available evidence suggests it probably came at least in part from the Saudi government,” because the bin Ladens are “working in concert with official Saudi policy” and “seem to fit inside a larger pattern.” This is a reference to the Al Yamamah arms deal (see Late 1985).
