Former prime minister Ariel Sharon was transferred Friday morning from the Sheba Medical Center Department of Respiratory Rehabilitation to its Intensive Care Unit, due to a weakening of his condition. Sharon contracted an infection that is affecting his heart, and will receive intensive treatment to combat the infection. David Weinberg, a spokesman for the Sheba Medical Center outside Tel Aviv said that Sharon's condition was stable. The last time Sharon was transferred to Intensive Care was in August, when he was suffering from a liver infection.
