Israeli former president Shimon Peres was sedated and is breathing with the aid of a respirator after suffering a stroke on Tuesday, his office said.

“Former president Peres’ doctors sedated and intubated him so as to best facilitate the continuation of his treatment,” the office of the 93-year-old Nobel Peace Prize winner said in a statement.

“He will undergo a CT scan so as to get a full and updated assessment of his situation.”
