But an intensification of the Yemen conflict and certainly an escalation to direct conflict between Iran and Saudi Arabia could scare off foreign investors. "The reality is that the Saudis and their allies have faced only the Yemeni people's resistance and experienced a disgraceful defeat".
A senior Iranian official said on Sunday it was "shameful" that U.S. President Donald Trump had named John Bolton as national security adviser because of his ties with rebels whom Iran sees as "terrorists", the state news agency IRNA reported.
Khoshrou also expressed dismay at the sale of U.S. weapons to Saudi Arabia, calling on the Muslin world and the global community to pressure Saudi Arabia to stop killings in Yemen.
Saudi Arabia is leading a mostly Arab military coalition to fight Iran-backed Houthi rebels in Yemen since March 2015.
The Saudi letter to the UN coincided with Saudi Crown Prince Mohammed bin Salman's meeting with UN Secretary General Antonio Guterres in NY.
Yemen's war fits into a broader decades-long struggle for supremacy between Middle East powerhouses Iran and Saudi Arabia, which fund and train proxy forces in Iraq, Syria and Lebanon and accuse each other of backing terrorism.
General Javani underlined that Saudi Arabia first though it was dealing with just a group of people; however, Riyadh is seeing that it is the "Yemeni nation" that is standing up to the Saudi Aggression.
He also expressed the UN's readiness to work to find a solution that will "end the suffering in Yemen".
Rashed wrote: "The situation would have been frightening; much worse and more serious for both Yemen and Saudi Arabia, and would have caused a wider war than the one we have witnessed in the past 36 months".
In 2016, Saudi Arabia's name appeared in a blacklist of child killers, but then-UN chief Ban Ki-moon removed it from the list shortly afterwards. They were once strong enough to force the legitimate government to flee, but the Saudi-led Arab coalition has weakened them.
Yemen's defenseless people have been under massive attacks by the Saudi-led coalition for three years but Riyadh has reached none of its objectives in Yemen so far. The military campaign has killed and injured over 600,000 civilians, according to the latest figures released by the Yemeni Ministry of Human Rights.
