An Italian network of extremists that has been closely monitored by local authorities (see After April 2001) goes silent following 9/11, after which only one message is intercepted. The message, which says, “Congratulations for the USA,” is from an unknown militant to Abdelhalim Remadna, a leading radical based in Milan. Remadna is arrested on November 12 as he attempts to flee Italy. One of his associates, Yassin Chekkouri, is arrested on the same day. Remadna will be sentenced to eight years in prison, whereas Chekkouri will receive four. Mahmoud Es Sayed, one of their associates who apparently had some foreknowledge of 9/11 (see August 12, 2000 and September 4, 2001), escapes Italy some time in October, but is apparently killed at the battle of Tora Bora in December 2001.
