1998 United States Embassy Bombings - Motivation and Preparation

Motivation and Preparation

The bombings are widely believed to have been revenge for American involvement in the extradition, and alleged torture, of four members of Egyptian Islamic Jihad (EIJ) who had been arrested in Albania in the two months prior to the attacks. Between June and July, Ahmad Isma'il 'Uthman Saleh, Ahmad Ibrahim al-Sayyid al-Naggar, Shawqi Salama Mustafa Atiya and Mohamed Hassan Tita were all renditioned from Albania to Egypt, with the cooperation of the United States; the four men were accused of participating in the assassination of Rifaat el-Mahgoub, as well as a later plot against the Khan el-Khalili market in Cairo. The following month, a communique was issued warning the United States that a "response" was being prepared to repay them for their interference.

According to journalist Lawrence Wright, the Nairobi operation was named after the Holy Kaaba in Mecca; the Dar es Salaam bombing was called Operation al-Aqsa in Jerusalem, but "neither had an obvious connection to the American embassies in Africa. Bin Laden initially said that the sites had been targeted because of the 'invasion' of Somalia; then he described an American plan to partition Sudan, which he said was hatched in the embassy in Nairobi. He also told his followers that the genocide in Rwanda had been planned inside the two American embassies."

Wright concludes that bin Laden's actual goal was "to lure the United States into Afghanistan, which had long been called 'The Graveyard of Empires.'" According to a 1998 memo authored by Mohammed Atef and seized by the FBI, around the time of the attacks, al-Qaeda had both an interest in and specific knowledge of negotiations between the Taliban and the American-led gas pipeline consortium CentGas.

In May 1998, a villa in Nairobi was purchased by one of the bombers for the purpose of accommodating bomb building in the garage. Sheikh Ahmed Salim Swedan purchased a beige Toyota Dyna truck in Nairobi and a 1987 Nissan Atlas refrigeration truck in Dar es Salaam. Six metal bars were used to form a "cage" on the back of the Atlas to accommodate the bomb.

In June 1998, KK Mohamed rented House 213 in the Illala district of Dar es Salaam, about four miles (6 km) from the U.S. Embassy. A white Suzuki Samurai was used to haul bomb components hidden in rice sacks, from House 213.

In both Nairobi and Dar es Salaam, Mohammed Odeh supervised construction of two massive, 900kg destructive devices. The Nairobi bomb was made of 400 to 500 cylinders of TNT (about the size of soda cans), aluminum nitrate, aluminum powder and detonating cord. The explosives were packed into some twenty specially designed wooden crates that were sealed and then placed in the bed of the trucks. Muhsin Musa Matwalli Atwah ran a wire from the bomb to a set of batteries in the back of the truck cab and then to a detonator switch beneath the dashboard. The Dar es Salaam bomb used a slightly different construction: the TNT was attached to fifteen oxygen tanks and gas canisters, and was surrounded with four bags of ammonium nitrate fertilizer and some sand bags to tamp and direct the blast.

The bombings were scheduled for August 7, the eighth anniversary of the arrival of American troops in Saudi Arabia, likely a choice by Osama bin Laden.
