German Foreign Minister Frank-Walter Steinmeier has demanded that Israel put an end to all settlement building in the occupied territories, in a newspaper interview published Saturday, dpa reported. It was "not acceptable" to found new settlements or expand existing ones in East Jerusalem or the West Bank, Steinmeier said in a joint interview with the German Press Agency dpa and German daily Sueddeutsche. Both the German and US governments agreed on this point, the foreign minister added. Steinmeier called for new efforts in the Middle East peace process, and said the European Union and US President Barack Obama's administration needed to "speak with one voice." Steinmeier's appeal echoes recent calls from Washington for Israel to put an end to all settlement building in the areas occupied since 1967. The new government of Israeli Premier Benjamin Netanyahu has refused the demand for a complete freeze in settlement activity, and has not agreed to a two-state solution for Israel and the Palestinian Territories. Within German diplomatic circles, the settlement activities are seen as undermining an increasingly precarious two-state solution.
