Jordan’s King Abdullah warned on Tuesday that Israel’s planned move to apply sovereignty over parts of Judea and Samaria next month would threaten stability in the Middle East, Reuters reported.

Speaking in a video conference with US congressional leaders and committees, the Jordanian King “warned that any unilateral Israeli measure to annex lands in the West Bank is unacceptable and undermines the prospects of achieving peace and stability in the region,” a royal palace statement said.

Abdullah, who aides say has been deeply concerned about the sovereignty plan, told US lawmakers that peace would only come with the creation of a “independent, sovereign and viable Palestinian state” with eastern Jerusalem as its capital.

The Jordanian King recently warned Israel against applying sovereignty in Judea and Samaria, saying that if Israel goes through with the sovereignty move, “it would lead to a massive conflict with the Hashemite Kingdom of Jordan".

Jordanian Prime Minister Omar al-Razzaz later threatened that the kingdom would review its relationship with Israel if the Jewish state goes ahead with the sovereignty move.

Earlier this week it was reported that King Abdullah is refusing to communicate with Prime Minister Binyamin Netanyahu over the sovereignty plan and is also eschewing overtures made by Defense Minister Benny Gantz.

Jordan is one of only two Arab countries, along with Egypt, to have signed a peace deal with Israel. However, many Jordanians still see Israel as an enemy and protest what they view as “normalization” with the Jewish state.

In addition, the country’s parliament, which is made up mostly of Islamists, remains anti-Israel and its members have more than once called to annul the peace treaty.
