Russia's Ministry of Foreign Affairs said on Tuesday that a U.S. decision to effectively back Israel's right to build Jewish settlements in the occupied West Bank undermined the legal basis for a settlement of the Israeli-Palestinian conflict. U.S. Secretary of State Mike Pompeo on Monday abandoned Washington's four-decade-old position that such settlements were 'inconsistent with international law.' Russia's Foreign Ministry condemned the change of policy in a statement on Tuesday, warning the move would escalate tensions in the region. Moscow's stance is that such settlements on Palestinian territory are illegal under international law, it said.
