"PM Netanyahu's wife Sara underwent last night, at Hadassah Ein Kerem hospital in Jerusalem, a successful appendectomy. Mrs. Netanyahu is in good condition and is recovering in the surgery ward," Gendelman tweeted.
Israeli media reported early on Thursday that the country's first lady was hospitalized after feeling unwell. Clinical tests then confirmed that she had an appendix infection.
The prime minister was with his wife before the surgery and was by her side afterwards.
