NATO is urging the United Nations to enforce the peace plan for Syria endorsed by an international conference in Geneva.

Secretary-General Anders Fogh Rasmussen said Monday that the conflict in the Arab state was risking the stability of the entire region.

On Saturday, the conference endorsed a U.N.-brokered peace plan that calls for the creation of a transitional government in Damascus.

The Syrian opposition has already dismissed the plan because it did not call for President Bashar Assad to give up power.

Fogh Rasmussen reiterated that NATO would not intervene militarily in Syria's conflict "because we believe a political solution is an adequate solution."

The Assad regime's crackdown on an increasingly armed popular uprising has left thousands dead in Syria over the past 16 months.
