Washington: Iran is the greatest challenge that the world faces in the Middle East, the United States and Israel have said and called for continued international efforts to prevent Tehran from developing a nuclear weapons capability.

The two countries met in Washington for their semi-annual strategic dialogue.

The US delegation was led by Deputy Secretary William Burns while Israeli delegation was led by its Deputy Foreign Minister Daniel Ayalon, for the semi-annual US-Israel Strategic Dialogue.

"While on Friday's Strategic Dialogue covered many subjects, it is clear that Iran is the greatest challenge we face on Friday in the Middle East," a joint statement said.

"Iran's continued noncompliance with its international obligations related to its nuclear programme, as well as its continued support for terrorist organisations, are of grave concern to our two countries and the entire international community," it said.

"Continued efforts by the international community are critical to bringing about change in Iranian behaviour and preventing Iran from developing a nuclear weapons capability,"
