UN Secretary-General Ban Ki-moon condemned on Monday Israel's plan to expropriate land beyond the Green Line.

"The Secretary-General is alarmed by yesterday’s announcement by Israeli authorities to declare as so-called 'state land' nearly 1,000 acres of land in the Bethlehem area of the West Bank," the UN chief's office said in a statement.

"The seizure of such a large swathe of land risks paving the way for further settlement activity, which – as the United Nations has reiterated on many occasions – is illegal under international law and runs totally counter to the pursuit of a two-state solution."

"The Secretary-General calls on Israel to heed the calls of the international community to refrain from settlement activity and abide by its commitments under international law and the Quartet road map."
