Ramzi Yousef, one of the main perpetrators of the 1993 World Trade Center bombing and the bombing of Philippine Airlines Flight 434, was arrested in Islamabad, Pakistan.

Ramzi Ahmed Yousef is a Pakistani convicted terrorist who was one of the main perpetrators and the mastermind behind the 1993 World Trade Center bombing and the bombing of Philippine Airlines Flight 434; he was also a co-conspirator in the Bojinka plot. In 1995, he was arrested by the Pakistani Inter-Services Intelligence (ISI) and U.S. Diplomatic Security Service at a guest house in Islamabad, Pakistan, while trying to set a bomb in a doll, then extradited to the United States.

On February 26, 1993, Ramzi Yousef and associates carried out a van bomb terrorist attack below the North Tower of the New York World Trade Center. The 1,336 lb (606 kg) urea nitrate–hydrogen gas enhanced device was intended to make the North Tower collapse onto the South Tower, taking down both skyscrapers and killing tens of thousands of people. While it failed to do so, it killed six people, including a pregnant woman, and caused over a thousand injuries. About 50,000 people were evacuated from the buildings that day.

Philippine Airlines Flight 434, sometimes referred to as PAL434 or PR434, was a scheduled flight on December 11, 1994, from Manila to Tokyo with a quick stopover in Cebu on a Boeing 747-283B that was seriously damaged by a bomb, killing one passenger and damaging vital control systems, although the plane was in a repairable state. The bombing was a test run of the unsuccessful Bojinka terrorist attacks. The Boeing 747 was flying the second leg of a route from Mactan–Cebu International Airport in Cebu, Philippines to Narita International Airport, in Tokyo, Japan. After the bomb detonated, 58-year-old veteran pilot Captain Eduardo "Ed" Reyes was able to land the aircraft, saving it and the remaining passengers and crew.
