UNITED NATIONS, Feb. 9 (Xinhua) -- UN Secretary-General Antonio Guterres reiterated on Monday that all Israeli settlements in the occupied West Bank, including East Jerusalem, and their associated regime and infrastructure, have no legal validity and are in flagrant violation of international law.

In a statement, Guterres' spokesperson Stephane Dujarric said the UN chief is gravely concerned by the reported decision of the Israeli security cabinet to authorize a series of administrative and enforcement measures in Areas A and B of the occupied West Bank.

"He warns that the current trajectory on the ground, including this decision, is eroding the prospect for the two-State solution," the statement said.

"Such actions, including Israel's continued presence in the Occupied Palestinian Territory are not only destabilizing but -- as recalled by the International Court of Justice -- unlawful," it said.

The secretary-general calls on Israel to reverse these measures and on all parties to preserve the only path to lasting peace, a negotiated two-state solution, in line with relevant UN Security Council resolutions and international law, the statement added. ■
