Former Israeli prime minister Ariel Sharon has undergone surgery to insert a new feeding tube.

Israel’s former prime minister Ariel Sharon, who has been in a coma for more than four years after suffering a series of strokes, was moved to his home today.

Doctors have admitted making a mistake when they treated then-Israeli Prime Minister Ariel Sharon with large doses of blood thinners after a mild stroke, according to a TV investigation broadcast today.

An Israeli TV station today quoted hospital officials as saying Prime Minister Ariel Sharon is not in a vegetative state and that his reflexes are responding to stimulation.
