Source-derived summary

Ramzi Ahmed Yousef (Urdu: رمزى احمد يوسف; born 27 April 1968) is a Pakistani convicted terrorist who was one of the main perpetrators and mastermind behind the 1993 World Trade Center bombing and the 1994 bombing of Philippine Airlines Flight 434; he was also a co-conspirator in the Bojinka plot. His profession was electrical engineering.

In 1995, Yousef was arrested by the Pakistani Inter-Services Intelligence (ISI) and U.S. Diplomatic Security Service in a joint operation at a guest house in Islamabad, Pakistan, while trying to set a bomb in a doll, then extradited to the United States. Yousef was tried in the U.S. District Court for the Southern District of New York along with two co-conspirators and was convicted. He received two life sentences plus 240 years for his part in the World Trade Center bombing and the Bojinka plot.

Yousef is serving his sentence at ADX Florence, located near Florence, Colorado. He shared a cell block that is commonly referred to as "Bombers' Row" with Terry Nichols, Eric Rudolph, and Ted Kaczynski, before the latter's transfer in late 2021.

Yousef's maternal uncle is Khalid Sheikh Mohammed, with whom he allegedly planned the Bojinka plot. Mohammed is a senior al-Qaeda member accused of being the principal architect of the September 11 attacks in 2001.

Early life

The name "Ramzi Ahmed Yousef" is a pseudonym.

Editorial summary

Begin with the source’s own compact description: “Ramzi Yousef” is pakistani terrorist convicted of 1993 World Trade Center bombing. The dossier treats that line as a proposition to test through Ramzi, Yousef and Pakistani, not as a finished interpretation.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1968, 1993, 1994, 1995—that can be checked directly. The authority record carries competing date values—1968-04-27, 1967-05-20—which should remain separate until their references and qualifiers are resolved. For this dossier, Ramzi, Yousef and Pakistani is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “pakistani terrorist convicted of 1993 World Trade Center bombing” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 15, 2026.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
