Democratic presidential hopeful Rep. Tulsi Gabbard, D-Hawaii, said Thursday that she would re-enter the Iran nuclear deal and end sanctions in response to Iran's involvement in drone attack against Saudi Arabia oil facilities if she was president. "What I would do is, I would re-enter the Iran nuclear deal to prevent Iran from continuing to move forward in building a nuclear weapon that puts us and the world further at risk," Gabbard said on "The Story with Martha MacCallum." Every day that we don't do this, every day we continue down this failed strategy Iran gets closer and closer to a nuclear weapon. U.S. officials told Fox News on Tuesday that Iranian cruise missiles and drones were both used in the attack on the two Saudi Arabian oil facilities, and that they were fired from inside southwest Iran this past weekend. Gabbard called the attack a "retaliation" against "extreme sanctions."

RIYADH – Saudi Arabia alleged Wednesday an attack by drones and cruise missiles on the heart of the kingdom's oil industry was "unquestionably sponsored by Iran," naming but not directly accusing Tehran of launching the assault. Iran denies being involved in the attack claimed by Yemeni rebels, and has threatened the U.S. that it will retaliate "immediately" if Tehran is targeted in response. The news conference by Saudi military spokesman Col. Turki al-Malki comes after a summer of heightened tensions between Iran and the U.S. over President Donald Trump unilaterally withdrawing America from Tehran's 2015 nuclear deal with world powers. The U.S. alleges Iran launched the attack, which Yemen's Houthi rebels earlier claimed as a response to the yearslong Saudi-led war there that's killed tens of thousands of people. Al-Malki made a point not to directly accuse Iran of firing the weapons or launching them from inside of Iranian territory.

DUBAI, UNITED ARAB EMIRATES – The assault on the beating heart of Saudi Arabia's vast oil empire follows a new and dangerous pattern that's emerged across the Persian Gulf this summer of precise attacks that leave few obvious clues as to who launched them. Beginning in May with the still-unclaimed explosions that damaged oil tankers near the Strait of Hormuz, the region has seen its energy infrastructure repeatedly targeted. Those attacks culminated with Saturday's assault on the world's biggest oil processor in eastern Saudi Arabia, which halved the oil-rich kingdom's production and caused energy prices to spike. Some strikes have been claimed by Yemen's Houthi rebels, who have been battling a Saudi-led coalition in the Arab world's poorest country since 2015. Their rapidly increasing sophistication fuels suspicion among experts and analysts however that Iran may be orchestrating them -- or perhaps even carrying them out itself as the U.S. alleges in the case of Saturday's attack.

DUBAI, UNITED ARAB EMIRATES – A weekend drone attack on Saudi Arabia that cut into global energy supplies and halved the kingdom's oil production threatened Sunday to fuel a regional crisis, as Iran denied U.S. allegations it launched the assault and tensions remained high over Tehran's collapsing nuclear deal. Iran called the U.S. claims "maximum lies," while a commander in its paramilitary Revolutionary Guard reiterated its forces could strike U.S. military bases across the Mideast with their arsenal of ballistic missiles. A prominent U.S. senator suggested striking Iranian oil refineries in response to the assault, claimed by Yemen's Iran-backed Houthi rebels, on Saudi Arabia's largest oil processing facility. "Because of the tension and sensitive situation, our region is like a powder keg," warned Guard Brig. "When these contacts come too close, when forces come into contact with one another, it is possible a conflict happens because of a misunderstanding."

The attack comes after Iran exceeded their enriched uranium stockpile limit in the nuclear deal. An Iranian official responded Sunday after U.S. Secretary of State Mike Pompeo pointed at the nation's government in Tehran following Saturday's drone attacks on Saudi Arabia oil facilities. "The Americans adopted the'maximum pressure' policy against Iran, which, due to its failure, is leaning towards'maximum lies'," Iranian Foreign Ministry spokesman Abbas Mousavi said, according to the Associated Press. On Saturday, Pompeo charged that Iran's government in Tehran ordered "nearly 100 attacks" on a Saudi refinery and oilfield, further alleging that Iranian President Hassan Rouhani and Foreign Minister Mohammad Zarif pretending "to engage in diplomacy." On Sunday, Mousavi dismissed Pompeo's remarks as "blind and futile comments."

WASHINGTON – U.S. Secretary of State Mike Pompeo on Saturday accused Iran of leading attacks on Saudi oil plants that cut the kingdom's output roughly in half, ruling out Yemeni involvement and denouncing Tehran for false diplomacy. Yemen's Iran-aligned Houthi group claimed credit for Saturday's attacks on two plants at the heart of Saudi Arabia's oil industry, including the world's biggest petroleum processing facility. Pompeo, however, said on Twitter that there was no evidence the attacks came from Yemen. "Tehran is behind nearly 100 attacks on Saudi Arabia while Rouhani and Zarif pretend to engage in diplomacy," Pompeo said, referring to Iran's President Hassan Rouhani and Foreign Minister Mohammed Javad Zarif. "Amid all the calls for de-escalation, Iran has now launched an unprecedented attack on the world's energy supply," he added.

The attack comes after Iran exceeded their enriched uranium stockpile limit in the nuclear deal. Secretary of State Mike Pompeo called on the international community to join him Saturday in condemning Iran for drone attacks on two Saudi oil facilities, which he described as "an unprecedented attack on the world's energy supply." "Tehran is behind nearly 100 attacks on Saudi Arabia while [President Hassan] Rouhani and [Foreign Minister Mohammad] Zarif pretend to engage in diplomacy," Pompeo tweeted, referring to the nation's president and foreign affairs minister. There is no evidence the attacks came from Yemen." Iran-backed Houthi rebels in Yemen claimed responsibility for the attack hours before Pompeo's tweet. The world's largest oil processing facility in Saudi Arabia and a major oil field were impacted, sparking huge fires at a vulnerable chokepoint for global energy supplies. "The United States will work with our partners and allies to ensure that energy markets remain well supplied and Iran is held accountable for its aggression," Pompeo concluded. According to multiple news reports that cited unidentified sources, the drone attacks affected up to half of the supplies from the world's largest exporter of oil, though the output should be restored within days. It remained unclear if anyone was injured at the Abqaiq oil processing facility and the Khurais oil field. Sen. Chris Murphy, D-Conn., who sits on the Senate Foreign Relations Committee, denounced Pompeo's description of the attack, calling it an "irresponsible simplification." "The Saudis and Houthis are at war.

Former Israeli Air Force pilot Tal Keinan says Israeli policy is to interrupt the ambition of any regional power that wants to eradicate Israel. Secretary of State Mike Pompeo said Sunday he supports "Israel's right to defend itself from threats posed by the Iranian Revolutionary Guard Corps," after the Israeli military carried out an attack on targets inside Syria on Saturday in what it described as a successful effort to thwart a "very imminent" Iranian drone strike. Pompeo tweeted that he spoke with Israel's Prime Minister Benjamin Netanyahu on Sunday regarding the airstrikes in Syria. He wrote, "I expressed my support for Israel's right to defend itself from threats posed by the Iranian Revolutionary Guard Corps & to take action to prevent imminent attacks against Israeli assets." Pompeo also tweeted, "We discussed how Iran is leveraging its foothold in Syria to threaten Israel and its neighbors. The Prime Minister Netanyahu noted that Israel would strike IRGC (The Islamic Revolutionary Guard Corps) targets threatening Israel, wherever they are located."

WASHINGTON – President Donald Trump invited Iranian Foreign Minister Mohammad Javad Zarif to the White House last month at the height of tensions between the two countries, The New Yorker magazine reported. The invitation, extended by Sen. Rand Paul with permission from the president, was turned down for now, The New Yorker reported Friday. Zarif said it was up to Tehran to decide on accepting it. Neither the White House nor the State Department responded to requests for comment on the report, which quoted U.S. and Iranian sources and what the magazine called a well-placed diplomat. Zarif told the magazine he would not want a White House meeting that yielded just a photo op and a two page statement afterwards, The New Yorker said.
