JERUSALEM — Israel is advancing a plan to invest in places it considers part of its national heritage, including nine West Bank sites, the government said Monday in an announcement that could appeal to hard-line voters a week ahead of elections. It triggered an angry Palestinian response.

Cabinet Secretary Tzvi Hauser said Israel is adding handicapped access to the Tomb of the Patriarchs, a sensitive site in the West Bank city of Hebron sacred to both Jews and Muslims.
