Achille Lauro cruise ship is hijacked

The cruise ship, Achille Lauro, was hijacked by four gunmen who demanded the release of Palestinian prisoners in Egypt and other countries.

They killed an American, Leon Klinghoffer, when their demands were not met. The terrorists were later linked to Yasser Arafat and the PLO and Libya. The mastermind of the hijacking was Abu Abbas. He was apprehended but later released by Italy.
