The lawyer defending an accused accomplice of the September 11 suicide pilots at his Hamburg retrial has been critically injured in a motorbike accident, throwing into question how the case will proceed.

LAWYERS for the only man convicted over the September 11 attacks in the United States said yesterday they will call for the case against him to be thrown out when he returns to trial this month.

A German court today overturned the world’s only conviction for the September 11 attacks and ordered a retrial for a Moroccan found guilty last year of aiding the Hamburg cell of suicide hijackers.
