US: Former New York city mayor Rudolph Giuliani described watching desperate people jump from the burning World Trade Center in emotional testimony yesterday to a jury that will determine if September 11th conspirator Zacarias Moussaoui should die.
Jurors and spectators, including relatives of the September 11th victims, also watched video clips of the two aircraft hitting the trade centre and then about five minutes of footage of people jumping from the burning, smoking buildings. Many spectators gasped and dabbed at tears while watching the video.
"I saw several people, I can't remember how many, jumping," Mr Giuliani said. "There were two people right near each other. It appeared to me they were holding hands. Of the many memories, that is one that comes to me every day."
Shortly after, jurors were shown several views of the Twin Towers collapsing in Manhattan on September 11th.
Moussaoui alternated between smiles and nods as he watched the video clips of the towers collapsing in Manhattan. After the jury and judge went for their morning break, he sang "Burn in the USA!" - an apparent parody of a Bruce Springsteen song.
Last year, Moussaoui, an admitted al- Qaeda member and the only person charged in the United States with the September 11th attacks, pleaded guilty to six counts of conspiracy. Three of the charges carry the death penalty.
On Monday, the jury found Moussaoui eligible for the death penalty. The jurors agreed with the government argument that Moussaoui's lies when he was arrested three weeks before the attacks led to the deaths of nearly 3,000 people.
In this final phase of the sentencing trial, jurors will decide if Moussaoui should be sentenced to death or to life in prison.
Dozens of witnesses, including family members of people who died in the hijackings and people who were injured in the attacks, will testify in this phase about how they were affected by the hijackings.
Mr Giuliani, who won high praise for his handling of the crisis, was the first major witness to do this. He described where he was that day, what he saw and what he felt.
"By the time the second plane hit, we knew for sure it was a terrorist attack," he said, sitting next to scale models of the World Trade Center.
"It was horrid," he said, describing the site of the Twin Towers after they collapsed. "The worst thing I've ever seen in my whole life . . . parts of human bodies . . . hands or legs."
Mr Giuliani said it looked like a "nuclear cloud" was going through Manhattan after the towers collapsed.
Calling September 11th, 2001, "the darkest day in American history", federal prosecutor Robert Spencer urged jurors to sentence Moussaoui to death for his part in the disaster. "Now it is time for you to hear the voices," he said. "You cannot understand the magnitude of the horror that day, unless you hear it from the families."
Gerald Zerkin, one of Moussaoui's court-appointed lawyers, urged jurors to keep an open mind and listen to evidence that the defendant had a mental illness that caused him to be involved in the conspiracy.
"The government's evidence will present an extraordinary challenge for you," he said. "You must somehow maintain equilibrium. You must nevertheless open yourselves to the possibility of a sentence other than death."
