The United Nations has denounced Israeli Prime Minister Benjamin Netanyahu over his support for the regime's expropriation of Palestinian territories and expansion of illegal settlements in the occupied West Bank.

UN Secretary General Ban Ki-moon said on Thursday during a meeting regarding the Israeli-Palestinian conflict that Israel's construction of settlement across the occupied territories is illegal, and that the Israeli forces' control over Palestinian territories must end.

"Let me be absolutely clear: settlements are illegal under international law. The occupation, stifling and oppressive, must end," he said.

Ban Ki-moon further said that the settlement of nearly a million Israelis in Palestinian territories is opposed to the creation of a Palestinian state.

The UN chief also slammed Benjamin Netanyahu over assertion that opposition to settlements was equal to ethnic cleansing.

“I am disturbed by a recent statement by Israel's prime minister portraying those who oppose settlement expansion as supporters of ethnic cleansing. This is unacceptable and outrageous,” he added.

Palestinian President Mahmoud Abbas said on Sunday that the Israelis "don't want to progress one iota towards peace, in spite of their deceptive allegations."

“On the contrary, they go deeper with their settlements, infringement of holy places, ethnic cleansing and deliberate killing," he added.

Mush of the international community see Israeli settlements as illegal because they are built on territories that were captured by Israeli regime in a war in 1967 and are subject to the Geneva Conventions, which forbid construction on occupied territories.
