Former Israeli president and Nobel Peace Prize winner Shimon Peres saw "real improvement" on Thursday morning, but he remained in serious condition after the 93-year-old suffered a major stroke on Tuesday, his doctor said.

"There is another real improvement today," Peres's personal physician and son-in-law Rafi Walden told media, describing his condition as serious but stable.

He said it was likely his condition would remain that way for the coming days.

Peres remained in intensive care and was breathing with the help of a respirator, but was still able to respond to prompts as he had the previous day.

Prime Minister Binyamin Netanyahu visited Peres at the Sheba Hospital yesterday and came away feeling "encouraged and relieved" upon seeing the former President's stable and improved condition.
