The US special envoy to Iran, Brian Hawk, stressed that "the Security Council needs to renew the arms embargo on Iran."
The envoy accused Iran of "trying to shock the global economy by hitting energy sources," as in the attack on Saudi Aramco.
"We have carried out an unprecedented pressure campaign on Iran to urge it to negotiate," he told a US congressional hearing on Iran.
"When the world stands with us, Iran will have to change."
Discussions touched on Iran's role in Syria. "Pressure on Iran is hampering Tehran's ability to pump billions and sell oil to the Syrian regime," Hawk said.
On Iran, the envoy stressed that Washington is seeking "a comprehensive agreement with Iran on its threats in the world." He explained that such an agreement should "include the nuclear and missile programs" of Tehran.
He added that "America is not seeking any direct military confrontation with Iran," and urged a "more serious approach to the issue of the proliferation of Iranian weapons."
Hawke accused Tehran of thwarting the mediation of Japanese Prime Minister Shinzo Abe by targeting an oil tanker during Abe's visit to Tehran.
He explained that the regime in Iran «depends on the export of the revolution», and «authorities granted to the Iranian Revolutionary Guards», which enables him to transfer funds and carry out operations in different countries.
He said that «Iran is cooperating with the Houthis in Yemen to threaten Saudi Arabia», pointing out that «Tehran wants to expand and expand».
At the beginning of the hearing, Senator Robert Mendes declared that "a new nuclear agreement with Iran is necessary."
In Riyadh, Saudi Arabia reaffirmed the shortcomings of the Iranian nuclear deal and the importance of a comprehensive international agreement to ensure that Iran is prevented from acquiring nuclear weapons in any way.
"Iran has exploited the economic dividend from the nuclear deal to finance its hostile and terrorist activities in the region," said Mansour bin Talak al-Mutairi, head of the UN disarmament and international security committee in the United Nations. The latest is the horrendous attacks on the oil installations of Aramco in Abqaiq and Khurais.
He stressed that this «is a flagrant violation of international laws and customs, an attack on international security and peace, and a major threat to the supply of oil to world markets».
He pointed out that «the establishment of security and stability in any region does not come through the possession of weapons of mass destruction, but can be achieved through cooperation and consultation between countries, and strive for development and progress, and to avoid the race in the possession of this destructive weapon of mankind».
The Kingdom also deplored the continued refusal of Israel to accede to the NPT and subject all its nuclear facilities to the IAEA comprehensive safeguards regime, and stressed that this posed a serious threat to international peace and security.
