Quds city, July 11, SPA -- The separation barrier Israel is building in Al-Quds city raises humanitarian problems for Palestinians and could complicate future negotiations on a final peace deal, the visiting European Foreign policy chief said Monday, after meeting with Israeli leaders. Israel's Cabinet on Sunday approved final details of the barrier, which will cut off four Arab neighborhoods with some 55,000 residents from the city, while including tens of thousands of West Bank settlers on the Al-Quds city side. The Associated Press quoted Palestinian officials as saying that Israel's main goal in building the barrier is not improving security, but shifting the disputed city's demographic balance in favor of Jews.
