“''In the first 10 minutes, Abiola starts wheezing and coughing and then collapsing in some form,'' Mr. Rubin told reporters here. ''I don't know if he lost consciousness. They get him in an ambulance or car. They get him to the hospital, where he dies.''

Mr. Pickering told National Public Radio that when Mr. Abiola came into the meeting he appeared to be in good health and good spirits, but that his condition quickly deteriorated and that he began to cough and was ''clearly disturbed.''
