Beirut, Lebanon ? A hijacker who seized a TWA jet in 1985 in a terrorist act that riveted America has returned home to Lebanon, paroled by Germany after serving 19 years of a life sentence.

But the United States wants Lebanon to turn over Mohamed Ali Hamadi for trial in the killing of Robert Dean Stethem, a U.S. Navy diver who was the only passenger on board to die.

State Department spokesman Sean McCormack said the United States was talking with the Lebanese government about Hamadi, but the U.S. does not have an extradition treaty with Lebanon.

Trans World Airlines Flight 847, with 145 passengers and nine crew members, was flying from Athens to Rome on June 14, 1985, when it was hijacked by Shiite Muslim militants demanding the release of hundreds of Lebanese from Israeli jails.

During a 17-day ordeal, the plane was forced to crisscross the Mediterranean from Lebanon to Algeria, landing in Beirut three times before it was finally allowed to remain there
