Arab nations have condemned a plan by Israeli PM Benjamin Netanyahu to annex part of the occupied West Bank.
On Tuesday Mr Netanyahu pledged to apply Israeli sovereignty over the Jordan Valley and northern Dead Sea if he is returned to office following a general election next week.
Officials in Jordan, Turkey and Saudi Arabia sharply criticised the announcement.
The Arab League denounced “the dangerous development” as “aggression”.
Palestinian diplomat Saeb Erekat said such a move would be a “war crime” that would “bury any chance of peace”.
Israel has occupied the West Bank since 1967 but has stopped short of annexation.
Palestinians claim the whole of the area for a future independent state. Mr Netanyahu previously insisted Israel would always retain a presence in the Jordan Valley for security purposes.
