Spain's Supreme Court on Friday threw out the convictions of three men found guilty last year of being part of al-Qaida after prosecutors agreed there was not sufficient evidence to jail them, a court official said. The men - Driss Chebli, Sadik Merizak and Abdelaziz Benyaich - had received sentences of between six and eight years for collaboration with an al-Qaida-linked terror group. They were among 18 people convicted in a high-profile trial last year linked to the Sept. 11 attacks. Prosecutors this week argued there was not sufficient evidence to jail the three and the Supreme Court agreed, said the court official, who was speaking on condition of anonymity because his office's ground rules prohibit him from being identified. The court was hearing appeals by all 18.
