"It is not the first time for Saudi officials to talk nonsense and impudently when they step into the land of bullying rulers who sell them security, Foreign Ministry Spokesman Bahram Qassemi said on Saturday.
Of course, it is now clear to everybody and even the American rulers that which country and what kind of thought is among the major sources, if not saying the only source, of terrorism, extremism and instability in the region and the world, he added.
"Iran is a vast country with natural borders and ancient civilization and history and there is no doubt that its cultural boundaries have gone beyond its geographical borders. This influence is inherent, historic and everlasting," Qassemi said.
The Islamic Republic of Iran has constantly tried to help the establishment of peace, security and stability in the region and fighting against terrorism, extremism and barbaric violence that have been imposed on the regional nations by some who rely on their petrodollars and support from the United States, he underlined.
Qassemi said that Saudi Arabia has caused all political initiatives to solve Yemen crisis over the past three years to come to a deadlock.
Al-Jubeir who is accompanying Saudi Crown Prince Mohammed bin Salman in his visit to Washington allegedly claimed that Iran supports terrorism.
Al-Jubeir made the remarks at a Brookings Institution meeting on political solutions to regional crises, particularly the Yemen crisis.
Saudi Arabia has been striking Yemen since March 2015 to restore power to fugitive president Mansour Hadi, a close ally of Riyadh. The Saudi-led aggression has so far killed at least 15,700 Yemenis, including hundreds of women and children.
Despite Riyadh's claims that it is bombing the positions of the Ansarullah fighters, Saudi bombers are flattening residential areas and civilian infrastructures.
According to several reports, the Saudi-led air campaign against Yemen has driven the impoverished country towards humanitarian disaster, as Saudi Arabia's deadly campaign prevented the patients from travelling abroad for treatment and blocked the entry of medicine into the war-torn country.
Yemen is the world’s largest humanitarian crisis with more than 22 million people in need and is seeing a spike in needs, fuelled by ongoing conflict, a collapsing economy and diminished social services and livelihoods.
A UN panel has compiled a detailed report of civilian casualties caused by the Saudi military and its allies during their war against Yemen, saying the Riyadh-led coalition has used precision-guided munitions in its raids on civilian targets.
