Bosnia's wartime president Alija Izetbegovic is in critical condition, his doctor said a day after the 78-year-old former leader developed internal bleeding to the chest. He is in critical condition," Ismet Gavrankapetanovic, the head of a medical team monitoring Izetbegovic, said on Friday. The doctor said that his condition had not improved since Thursday when Izetbegovic developed internal bleeding and that there was "no question" of operating on the former president at this stage. Doctors considered surgery on Thursday with one medical source saying that an operation was the only recourse to save Izetbegovic's life. "An intensive therapy has been applied in order to improve his condition," said Gavrankapetanovic. Gavrankapetanovic refused to comment on the chances for Izetbegovic's recovery. Izetbegovic, who has already suffered two heart attacks, was rushed to a Sarajevo clinic last week after he had fainted at home and fractured four left ribs. The former president has suffered a series of complications including respiratory and circulation problems since Tuesday. Elected chairman of Bosnia's collective presidency in 1990, Izetbegovic was a key figure during the country's 1992-1995 war. Izetbegovic won worldwide sympathy by running the government from the sandbagged buildings during the three-and-a-half-year-long siege of Sarajevo by Bosnian Serbs under constant threat of their artillery and sniper attacks. He held the Muslim seat in Bosnia's post-war presidency, which has a rotating chairmanship that also includes a Serb and a Croat representative. Izetbegovic stepped down from the presidency in October 2000 due to failing health and his advanced age. He was fitted last year with a pacemaker by Slovenian cardiologists, and has received treatment for his heart condition in hospitals in Sarajevo and Saudi Arabia. **PHOTO CAPTION*** Bosnia's wartime president Alija Izetbegovic.
