Ahmed Mohammad Ajaj (also transliterated Ahmad; Arabic: أحمد محمد عجاج; born 1966) is a Palestinian citizen who is convicted of participating in the 1993 World Trade Center bombing.

On April 24, 1992, abandoning his first asylum claim, Ajaj flew from New York to Peshawar, Pakistan, using the alias Ibrahim Salameh, from there to Camp Khalden on the Afghanistan-Pakistan border.

On May 16, 1992, he flew to Saudi Arabia via the United Arab Emirates where he procured a letter of introduction requesting the leader of Camp Khalden provide the bearer with training in the use of weapons and explosives.

On August 31, 1992, using services of a Pakistani travel agent, Ahmad Ajaj and Ramzi Yousef boarded Pakistan International Airlines flight 703 in Peshawar and flew to Karachi, Pakistan, then on to Kennedy Airport in New York City, flying first class during both legs of the trip, believing they would receive less scrutiny.

It is unknown whether Ajaj was meant to cause a scene as a distraction to let Yousef slip through, or legitimately lost his temper, but he shouted to the inspector: "My mother was Swedish!

Yousef claimed he was fleeing Saddam Hussein and needed asylum, that he had been recently beaten by Iraqi soldiers in Kuwait because they thought he was a member of a Kuwaiti guerilla organization.

Yousef had checks from Lloyds Bank of London and an address book listing what Morales later called "unusual places [in America] for someone to visit whom had just come from halfway around the world."

Ajaj told authorities he had a political asylum claim from a prior entry in February 1992, and was detained pending a hearing.

The U.S. Bureau of Prisons moved him to a medical facility, where he had surgery to remove the cancerous lung and received radiation treatment.

He has filed scores of grievances and several lawsuits against the U.S. prison system, alleging everything from interference with his mail to denial of access to lawyers, and violations of his Eighth Amendment rights.
