Jordan's King Abdullah II stressed the need for calm, de-escalation in the Palestinian territories, and the cessation of any measures that destabilize stability and undermine the chances of achieving peace.

A statement issued by the royal court on Sunday said that King Abdullah stressed, during his meeting with US Secretary of Defense Lloyd Austin, who is visiting the region, the "necessity of calm and de-escalation in the Palestinian territories and the cessation of any unilateral measures that destabilize stability and undermine the chances of achieving peace."

The king also stressed "the need to intensify efforts to create a political horizon that paves the way for re-launching negotiations between the Palestinians and the Israelis to reach a just and comprehensive peace based on the two-state solution."

Austin arrived in Jordan on Sunday at the start of a tour of the Middle East that will also include Israel and Egypt, and aims to show US support for its main allies in the region in the face of what US officials described as "the growing threat posed by Iran."

King Abdullah reaffirmed the importance of establishing an independent, sovereign and viable Palestinian state, on the lines of June 4, 1967, with East Jerusalem as its capital.

Negotiations between the Palestinian and Israeli sides have stalled since April 2014, due to Israel's refusal to release old detainees, stop settlement activity, and accept the pre-June 1967 war borders as a basis for the two-state solution.

The Palestinian territories are witnessing escalating tension, which since the beginning of this year has resulted in the death of 63 Palestinians by Israeli occupation bullets in the West Bank and Jerusalem, including 11 during the storming of Nablus on February 22.

On February 26, Israeli and Palestinian officials pledged to work to "de-escalate" during a meeting held in Aqaba, Jordan, sponsored by the United States, and rejected by Palestinian factions.

It is noteworthy that Jordan is a member of the international coalition led by the United States to fight the Islamic State in Syria and Iraq.

Oman and Washington have close military cooperation.
