Asif Ali Zardari, who was undergoing medical tests in a Dubai hospital, was in a "stable" condition, said the president's physician.
Associated Press of Pakistan reported that a health bulletin issued by Zardari's physician Colonel Salman on Wednesday said: "Routine evaluation of the president's condition is being carried out. Investigations carried out so far are essentially within normal range and the president's condition is stable."
Zardari abruptly flew out of Pakistan Tuesday, leading to much confusion and intense speculation. The official line was that he had gone to Dubai for medical tests and also to meet his children, though Pakistan Army doctors who carried out a medical check declared him fit. A US magazine quoted a former American official as saying that Zardari had a minor heart attack and may resign as president.
