Jordanian King Abdullah II Monday urged coordinated and intensified international action to resolve the Palestinian-Israeli conflict as peacemaking efforts are going through a "very critical stage", the state-run Petra news agency reported.

The king made the remarks during a meeting with a delegation from J Street, which is an American-Jewish entity that supports the two-state solution and is against Israeli settlement activities.

At the meeting, the king said resolving the conflicts should be in line with the two-state solution and within comprehensive peace in the region.

The two-state solution is the key to attaining Middle East peace, the king added.

The Jordanian king also warned that the delay in launching serious and effective Palestinian-Israeli peace talks would undermine opportunities for the creation of an independent Palestinian state and will lead to new circles of violence in the Middle East.

On Sunday, Jordan's Prime Minister Samir Rifai met with the delegation, which also includes several U.S. Congressmen, and stressed the key role the U.S. plays in supporting Middle East peace efforts.
