The United Nations Special Coordinator for the Middle East Peace Process, Tor Wennesland, has voiced his deep concern over Israel’s seizure of Palestinian lands in favor of the internationally-condemned settlement expansion activity.

"Today, the Israeli authorities announced tenders for the construction of more than 1,300 housing units in the occupied West Bank," said Wennesland in a statement issued on Sunday.

Wennesland said he is alarmed by continued Israeli settlement expansion on occupied Palestinian land in the West Bank, including East Jerusalem.

“I reiterate that all settlements are illegal under international law, remain a substantial obstacle to peace, and must cease immediately," he added.
