We are, the fifth battalion in the Liberation Army, declare our responsibility for the explosion on the mentioned building. This action was done in response for the American political, economical, and military support to Israel, the state of terrorism, and to the rest of the dictator countries in the region. :Our Demands Are: :1 – Stop all military, economical, and political aid to Israel. :2 – All diplomatic relations with Israel must stop. :3 – Not to interfere with any of the Middle East countries interior affairs. If our demands are not met, all of our functional groups in the army will continue to execute our missions against the military and civilian targets in and out the United States. For your own information, our army has more than hundred and fifty suicidal soldiers ready to go ahead. The terrorism that Israel practices (which is supported by America) must be faced with a similar one. The dictatorship and terrorism (also supported by America) that some countries are practicing against their own people must also be faced with terrorism. The American people must know, that their civilians who got killed are not better than those who are getting killed by the American weapons and support. The American people are responsible for the actions of their government and they must question all of the crimes that their government is committing against other people. Or they — Americans — will be the targets of our operations that could diminish them.

Arrival in United States

On 1 September 1992, Yousef entered the United States with an Iraqi passport of disputed authenticity. His companion, Ahmed Ajaj, carried multiple immigration documents, among which was a crudely falsified Swedish passport. Providing a smokescreen to facilitate Yousef's entry, Ajaj was arrested on the spot when immigration officials found bomb manuals, videotapes of suicide car bombers, and a cheat sheet on how to lie to U.S. immigration inspectors in his luggage. Directors of the American Counter-Terrorism program later tied the travel arrangements to a phone call from

Explosion and aftermath

Yousef rented a Ryder van and on 26 February 1993, loaded it with powerful explosives. He packed four cardboard boxes into the back of the van, each containing a mixture of paper bags, newspapers, urea, and nitric acid; next to them he placed three red metal cylinders of compressed hydrogen.

were loaded into the center of the van with Atlas Rockmaster blasting caps connected to each. The van was driven into the garage of the World Trade Center, where it exploded. Using his Pakistani passport, Yousef escaped from the United States hours later. It is believed that he fled to Iraq and then Pakistan. As a result of the bombing, the FBI added Yousef as the 436th person on its Ten Most Wanted Fugitives list on 21 April 1993.

1993 Benazir Bhutto assassination attempt

After returning to Pakistan in February 1993, Yousef went into hiding. That summer, he allegedly took up a contract to assassinate the Prime Minister of Pakistan,

Benazir Bhutto Benazir Bhutto ( ur, بینظیر بُھٹو; sd, بينظير ڀُٽو; Urdu ; 21 June 1953 – 27 December 2007) was a Pakistani politician who served as the 11th and 13th prime minister of Pakistan from 1988 to 1990 and again from 1993 t ...

, which was initiated by members of Sipah-e-Sahaba. The plot failed when Yousef and Abdul Hakim Murad were interrupted by police outside Bhutto's residence. Yousef decided to abort the bombing and it blew up as he was trying to recover the device. He escaped and went into hiding during the investigation.

Bojinka plot

After the Iranian shrine bombing, Yousef soon began planning the Bojinka plot. It included plans to assassinate Pope John Paul II while he visited the Philippines, and to plant bombs inside several United and Delta Air Lines flights out of Bangkok. On this plot, he allegedly worked with his maternal uncle, Khalid Sheikh Mohammed.

1994 Philippine Airlines Flight 434 bombing

On 11 December 1994, Yousef conducted a trial run of the plan by boarding Philippine Airlines Flight 434 from Manila to Tokyo, Japan, with a stopover in Cebu. His identity for the flight was that of an Italian man named Armaldo Forlani. As an accomplished forger, he was able to make a

GlobalSecurity.Org report on incident The domestic flight attendant Maria Delacruz had noticed that Yousef kept switching seats during the course of the Manila to Cebu flight, but did not warn the new cabin crew boarding at Cebu of his behavior. Yousef and 25 other passengers left the plane at Cebu, where 256 passengers and a new cabin crew boarded for the trip to Tokyo. Many passengers were Japanese people; some were coworkers traveling as part of a tour group. Airport congestion delayed the departure of Flight 434 from Cebu for 38 minutes. All of the passengers had boarded by 8:30 a.m., with the bomb having been planted around two hours earlier. PAL 434 was cleared for takeoff at 8:38 a.m. At 11:43 am, about an hour and a half from Tokyo, the bomb exploded while Flight 434 cruised on autopilot above the Japanese island of

and approximately 260 miles (420 km) southwest of Tokyo). The explosion dismembered 24-year-old , a Japanese businessman occupying the seat where the bomb was placed. Ten passengers sitting in the seats in front of and behind Ikegami were also injured while one needed urgent medical care. The explosion tore out a two square-foot (0.2 m²) portion of the cabin floor into the cargo hold but leaving the fuselage of the plane intact. The airplane was spared from a deadly fiery explosion as the seat where the bomb was planted, 26K, was two rows away from the central fuel tank. The rapid expansion of energy from the bomb caused the plane to expand vertically slightly, damaging cables to the steering and aileron controls. The bomb's orientation caused the energy to be mostly absorbed by Ikegami; he was killed but the other passengers and the plane were not catastrophically damaged. The cockpit crew improvised to manipulate the plane's speed and direction by varying the engines' throttle settings. Captain Eduardo Reyes made an emergency landing at Okinawa's Naha Airport, saving 272 passengers and 20 crew. The aircraft became a crime scene under Japanese law; bomb fragments found in and around the blast zone, as well as the lower half of Ikegami's body, provided clues pointing investigators back to Manila.

Discovery by police

Yousef then returned to Manila, where he began preparing at least a dozen bombs, each with more explosive materials. Weeks before his planned attacks, a fire started in his Manila apartment, forcing him to flee the room, leaving everything behind. The fire made the apartment staff suspicious, and soon police, led by

1994 Imam Reza shrine bombing

1995 U.S. airliner bombing attempt

Despite the international manhunt, Yousef escaped from Manila to Pakistan. On 31 January 1995, he flew from Pakistan to Thailand and met with a South African associate Istaique Parker. Yousef told Parker to check two suitcases filled with bombs, one on a Delta Air Lines flight and another on a United Airlines flight. Both bombs were timed to blow up over populated areas of the U.S. Parker spent much of the day at the airport, but was reportedly too scared to approach the airlines with the suitcases. Finally, Parker returned to Yousef's hotel and lied that employees at the airline cargo sections were asking for passports and fingerprints, making it too risky to go ahead with the plan. Yousef, wanting to get the bombs on a plane bound for the U.S., called a friend with diplomatic immunity in Qatar who was willing to take the suitcases to London and check them on a flight to the U.S. The plan was that they would explode mid-flight and destroy the plane. Yousef planned to use the friend's diplomatic immunity to ensure the suitcases would be loaded on the plane. According to Simon Reeve's book '' The New Jackals'', the name of this friend has not been revealed, but his father is said to be a very senior politician and leading member of the establishment in Qatar (at the time, Yousef's maternal uncle, Khalid Sheikh Mohammed, was living in Qatar as the guest of a Qatari cabinet official). However, there was a problem and the suitcases were not checked in. Yousef and Parker returned to Pakistan on 2 February 1995.

Arrest, conviction and prison life

Following a tip-off from Istaique Parker, on 7 February 1995, Agents of Pakistan's Inter-Services Intelligence (ISI) and Special Agents of the

raided room #16 in the Su-Casa Guest House in Islamabad, Pakistan, and captured Yousef before he could move to Peshawar. Parker was paid $2 million under the

On 5 September 1996, Yousef and two co-conspirators were convicted for their role in the Bojinka plot and were sentenced by U.S. District Court Judge Kevin Duffy to life in prison without parole. On 12 November 1997, Yousef was found guilty of masterminding the 1993 bombing, and on 8 January 1998, Judge Duffy found Yousef guilty of plotting a "seditious conspiracy" to bomb the World Trade Center and sentenced Yousef to life plus 240 years in prison for both bombings.

. During the 1998 trial, Yousef said:

You keep talking also about collective punishment and killing innocent people to force governments to change their policies; you call this terrorism when someone would kill innocent people or civilians in order to force the government to change its policies. Well, when you were the first one who invented this terrorism.

You were the first one who killed innocent people, and you are the first one who introduced this type of terrorism to the history of mankind when you dropped an atomic bomb which killed tens of thousands of women and children in Japan and when you killed over a hundred thousand people, most of them civilians, in Tokyo with fire bombings. You killed them by burning them to death. And you killed civilians in Vietnam with chemicals as with the so-called Orange agent. You killed civilians and innocent people, not soldiers, innocent people every single war you went. You went to wars more than any other country in this century, and then you have the nerve to talk about killing innocent people.

And now you have invented new ways to kill innocent people. You have so-called economic embargo which kills nobody other than children and elderly people, and which other than Iraq you have been placing the economic embargo on Cuba and other countries for over 35 years. ... The Government in its summations and opening statement said that I was a terrorist. Yes, I am a terrorist and I am proud of it. And I support terrorism so long as it was against the United States Government and against Israel, because you are more than terrorists; you are the one who invented terrorism and using it every day. You are liars, butchers, and hypocrites.New York Times, January 9, 1998.

Duffy responded:

Ramzi Yousef, you claim to be an Islamic militant. Of all the persons killed or harmed in some way by the World Trade Center bomb, you cannot name one who was against you or your cause. You did not care, just so long as you left dead bodies and people hurt. Ramzi Yousef, you are not fit to uphold Islam. Your God is death. Your God is not Allah ... You weren't seeking conversions. The only thing you wanted to do was to cause death. Your God is not Allah. You worship death and destruction. What you do, you do not for Allah; you do it only to satisfy your own twisted sense of ego. You would have others believe that you are a soldier, but the attacks on civilization for which you stand convicted here were sneak attacks which sought to kill and maim totally innocent people ... You, Ramzi Yousef, came to this country pretending to be an Islamic fundamentalist, but you cared little or nothing for Islam or the faith of the Muslims. Rather, you adored not Allah, but the evil that you yourself have become. And I must say that as an apostle of evil, you have been most effective.

Yousef is held at the high-security Supermax prison ADX Florence in Florence, Colorado. The handcuffs Ramzi Yousef wore when he was captured in Pakistan are displayed at the FBI Museum in Washington, D.C. His Federal Prisoner number is: 03911–000.
