The jury deciding the fate of al-Qaida conspirator Zacharias Moussaoui has halted deliberations after one member reported feeling ill.
The judge and lawyers in the sentencing trial say they will check on the juror later Thursday and decide whether to resume deliberations Friday.
The jury in Alexandria, Virginia, is sorting through more than 40 pages of instructions on how to decide whether Moussaoui should be sentenced to death or life imprisonment. If the jurors cannot reach a unanimous decision, Moussaoui will automatically face life behind bars.
Moussaoui is the only person to be tried in the United States in connection with the September, 2001 terror attacks. He was in jail at the time, but the prosecution argued that by lying to investigators, he kept security officials from thwarting the plot.
Moussaoui pleaded guilty to six counts of conspiracy last year.
