US Secretary of State Mike Pompeo said an international alliance of Gulf, European and Asian countries alongside Israel is being formed to develop defense systems to reduce escalation in the Middle East.

Pompeo stressed in a speech at Kansas State University on Friday that Iran is the "central problem" that causes instability in the Middle East.

In this context, the US Secretary of State said that the US administration is working to establish an alliance of Gulf States, Israel, European partners and countries from Asia to ease tension and reduce the possibility of conflict in the region.

At the same time, he said, Washington had another mission: to deprive the Iranian regime of the wealth and resources used to "carry out its terrorist campaigns around the world".

The administration of President Donald Trump is implementing what it calls a policy of extreme pressure on Iran after Trump announced last year he withdrew from the 2015 agreement between Tehran and world powers to restrict Iran's nuclear program.

"For months, President Trump has said that he is ready to meet Iranian leaders without preconditions," Pompeo said.

France is mediating the conditions for a meeting between Trump and his Iranian counterpart Hassan Rouhani at the end of September at the UN General Assembly.

In May, Iran began to gradually disengage from its obligations under the nuclear deal in response to the US withdrawal from the deal and re-imposing sanctions.

Tehran announced last Wednesday a new phase in this policy to abandon any restrictions that limit its ability to conduct research and development in the nuclear field, to announce the details of this phase on Saturday.
