Ten years later, in 1998, at least 700 people were still being treated for the severe after effects of the attack and 500 of them were judged to be critically ill, even as "the most severe cases may already have died."
Deset godina kasnije, 1988., najmanje 700 ljudi još uvijek je bilo liječeno zbog teških posljedica napada, a od njih 500 je bilo teško bolesno, čak i kad su "najteži slučajevi već vjerojatno umrli".
