Ahmed Ibrahim Al-Mughassil

On August 26, 2015, the Saudi-owned newspaper Asharq al-Awsat reported that al-Mughassil had been captured in Beirut and transferred to Riyadh, Saudi Arabia.. However this claim was later refuted by the FBI.

Although rooftop sentries were immediately suspicious of the truck—parked some 80 feet from the building—and attempted an evacuation, few escaped. Comparable to 20,000 pounds of TNT, the bomb was estimated to be larger than the one that destroyed the federal building in Oklahoma City a year before, and more than twice as powerful as the 1983 bomb used at the Marine barracks in Beirut.

In 2001, al-Mughassil was eventually indicted along with his co-conspirators for the 1996 Khobar Towers attack. Still a U.S. fugitive months later, he then became one of four of the indicted men from the 1996 Khobar Towers attack who were named on the initial list of the FBI's top 22 Most Wanted Terrorists, which was released to the public by former President Bush on October 10, 2001.

The indictment traces the carefully organized 1996 bomb plot back to on or about 1993 when Al-Mughassil began to carefully review his cell members' surveillance reports of Americans in Saudi Arabia.

In early June 1996, according to the indictment, a tanker truck was purchased by the conspirators, who then spent two weeks converting the truck into a truck bomb. The cell finalized plans on the evening of June 25, 1996, for the attack that night.

In 1995, an Iranian military officer directed the cell's surveillance on the Red Sea coast of Saudi Arabia for sites of possible future attacks against Americans, and the indictment alleges that Iranian officials enjoyed close ties and provided financial support to Al-Mughassil's party.

About June 1995, regular surveillance of Khobar Towers began, at the direction of Al-Mughassil. By late Fall 1995, Al-Mughassil had decided that Hizballah would attack Khobar Towers with a tanker truck loaded with explosives. In early 1996, Al-Mughassil began to hide explosives around the Khobar area.

In the Fall of 1994, the cell determined Khobar Towers to be an important American military location and began an effort in the region to locate a storage site for explosives.

Ahmed Ibrahim Al-Mughassil (Arabic: أحمد إبراهيم المغسل ‎ born June 26, 1967), also spelled Ahmad Ibrahim Al-Mughassil, is wanted by the United States government in connection with the June 25, 1996, attack on the Khobar Towers complex near Dhahran, Saudi Arabia. He was indicted in the United States District Court for the Eastern District of Virginia and charged June 21, 2001, with 46½ separate criminal counts including murder for having driven the bomb truck that blew up Khobar Towers.
