United Nations sanctions against Afghanistan take effect. The sanctions freeze Taliban assets and impose an air embargo on Ariana Airlines in an effort to force the Taliban to hand over bin Laden. [BBC, 2/6/2000] It had been widely reported that Ariana had become a transportation arm for al-Qaeda (see Mid-1996-October 2001). However, Ariana will keep its illegal trade network flying, until stricter sanctions will ground it in 2001 (see January 19, 2001).
