President Shimon Peres underwent surgery on Friday to treat a hernia in his abdomen. He was hospitalized in the Sheba Medical Center in Tel Hashomer, and doctors said the operation was successful.

The hernia was discovered during the president's state visit to Canada. He was treated by his personal doctor Prof. Rafi Walden. Peres continued the visit unaltered, returning as scheduled on Friday.

Upon return, Peres was taken to the Sheba Medical Center for surgery. The President's office said that the treatment was routine and that he will be released from care on Sunday.

Upon the completion of the operation, Peres' personal doctor said that the surgery was successful and that the president awoke from the anesthetic feeling well.

Peres spoke with his family and his advisers and asked them to express his deep gratitude to all those who wished him well.
