The Palestinian Islamic Jihad on Tuesday threatened to retaliate against the United States if it tried to capture its Damascus-based leader, Dr. Ramadan Abdullah Mohammad Shallah. On Monday, Washington announced that they would offer a $5 million reward for information leading to the capture of Shallah. The same amount was also offered for a member of Lebanese Hizbullah, Mohammed Ali Hamadei. The alleged Lebanese Hizbullah member took part in the 1985 hijacking of TWA Flight 847 that resulted in the killing of U.S. sailor Robert Stethem.
