Iran is widely accused of backing the Houthis, a Zaydi Shiite movement that has been fighting Yemen’s Sunni-majority government since 2004. The Houthis took over the Yemeni capital Sanaa (left) in September 2014 and seized control over much of north Yemen by 2016. Yemeni officials and Sunni states have repeatedly alleged that Iran and its proxy Hezbollah have provided arms, training, and financial support to the Houthis. But Iranian and Hezbollah officials have denied or downplayed the claims. In November 2017, Revolutionary Guards commander Maj. Gen. Ali Jafari said that “Iran’s assistance is at the level of advisory and spiritual support.”
Tensions between Sunni states and Iran, specifically Saudi Arabia, escalated on November 4, 2017, when Yemen’s Houthi rebels fired a ballistic missile at King Khalid International Airport in Riyadh. The Houthis claimed responsibility for the attack, the first time a Houthi missile had come so close to the capital. The Saudi Defense Ministry said it intercepted the missile. Saudi Foreign Minister Adel al Jubeir called the attack an act of war by Iran. "It was an Iranian missile, launched by Hezbollah, from territory occupied by the Houthis in Yemen," he said. U.S. President Donald Trump also accused the Islamic Republic. “A shot was just taken by Iran, in my opinion, at Saudi Arabia…and our system knocked the missile out of the air,” he said. Tehran rebuffed the claims as “false, irresponsible, destructive and provocative.” In Lebanon, Hezbollah leader Hassan Nasrallah refuted allegations of the group’s involvement as “silly” and “completely baseless.” In response, Saudi Arabia imposed a near-total blockade on Yemen.

The situation further deteriorated when the Houthis killed ex-president Ali Abdullah Saleh on December 4, 2017. Saleh had officially aligned with the Houthis in May 2015, helping the Houthis gain control over much of northern Yemen. But the alliance was shaky at best. In August, one of Saleh’s top advisers was shot and killed following a confrontation with the Houthis. On December 2, Saleh publicly split from the Houthis, seeking a “new page” with the Saudi-led coalition. “I call upon the brothers in neighboring states and the alliance to stop their aggression, lift the siege, open the airports and allow food aid and the saving of the wounded and we will turn a new page by virtue of our neighborliness,” he said. Two days later he was killed by Houthi rebels in a roadside ambush.
Iranian officials celebrated Saleh’s death. Ali Akbar Salehi, a senior aide to Supreme Leader Ayatollah Khamenei said Saleh got what he deserved, according to the Middle East Institute. Senior advisor Ali Akbar Velayti commented on the Yemeni people’s control over their own future. “Ali Abdullah Saleh was killed and United Arab Emirates and Saudi Arabia conspiracy was foiled by the people of Yemen. The people will determine their own fate and they will win like the people of Syria, Iraq and Lebanon,” he said.
The following is an overview of the Houthi movement, including its origins, religious inspiration and alleged links to Iran.
Where are the Houthis from? What role have they played in Yemen's history?
The Houthis are a large clan originating from Yemen’s northwestern Saada province. They practice the Zaydi form of Shiism. Zaydis make up around 35 percent of Yemen’s population.
A Zaydi imamate ruled Yemen for 1,000 years, before being overthrown in 1962. Since then, the Zaydis – stripped of their political power – have struggled to restore their authority and influence in Yemen. In the 1980s, the Houthi clan began a movement to revive Zaydi traditions, feeling threatened by state-funded Salafist preachers who established a base in Houthi areas. Not all Zaydis, however, align with the Houthi movement.
Houthi insurgents have clashed with Yemen’s government for more than a decade. Since 2011, the Houthi movement has expanded beyond its Zaydi roots and become a wider movement opposed to President Abd Rabbuh Mansour Hadi. The insurgents have also begun referring to themselves as Ansarullah, or “Party of God.”
How does Zaydism compare to the type of Shiism practiced in Iran?
Like other Shiites, Zaydis believe that only descendants of the Prophet Mohammed’s cousin and son-in-law, Ali, have the right to lead the Muslim community as imams - divinely-appointed successors of the Prophet. Most adherents of Zaydism reside in Yemen, and Zaydis make up around eight percent of the world’s 70 million Shiites.
But the Zaydis are distinct from the “Twelver” form of Shiism practiced by the majority of the world’s Shiites, including most Shiites in Iran. Twelver Shiites believe the twelfth imam, whom they consider infallible, disappeared in 874AD and will one day return to usher in an age of justice as the Mahdi, or promised one. In the Mahdi’s absence, Twelver Shiites believe clerics can substitute for his authority on certain issues. The faithful are obliged to obey the clerics’ religious rulings, a power transferred to Iran’s theocracy after the 1979 revolution.
Zaydis, also known as “Fivers,” believe that Zayd, the great-grandson of Ali, was the rightful fifth imam. But Twelver Shiites consider Zayd’s brother, Mohammad al Baqir, the fifth imam. The Zaydis do not recognize the later Twelver imams, and instead believe anyone related to Ali is eligible to lead the Muslim community. They also reject the Twelver doctrine that the imam is infallible.
Who is supporting the Houthis? How?
Iranian officials have supported the Houthis’ cause and compared the group to Hezbollah. “Iran supports the rightful struggles of Ansarullah in Yemen and considers this movement as part of the successful Islamic Awakening movements,” Ali Akbar Velayati, senior advisor to Supreme Leader Ayatollah Ali Khamenei, said in October 2014. But Tehran has repeatedly denied providing arms, funds or training to the Houthis.
Saudi Arabia has long accused Iran of arming the Houthis to fight a proxy war. “We are worried about…the tendencies of Iran in the region, which is one of the leading elements implanting instability in the region,” the late Saudi Foreign Minister, Prince Saud al Faisal, said in 2015.
In October 2016, a U.S. admiral said that U.S. Navy and allied nations’ warships had intercepted five weapons shipments from Iran to the Arabian Peninsula since April 2015. The shipments reportedly included anti-tank missiles, sniper rifles and thousands of AK-47 automatic rifles. “These accusations are totally false,” Iranian Foreign Ministry spokesman Bahram Ghasemi (left) said in response.
In April 2017, Secretary of State Rex Tillerson said that Iran supports the Houthis’ “attempted overthrow of the government by providing military equipment, funding, and training, thus threatening Saudi Arabia’s southern border.” In November 2017, however, Revolutionary Guards commander Maj. Gen. Ali Jafari claimed that “Iran’s assistance is at the level of advisory and spiritual support.”
Tensions over Iranian support of the Houthis escalated in late 2017. In November, Saudi Arabia charged Iran with an act of war for a missile fired at the Saudi capital by the Houthis in Yemen. Iran denied any links to the attack. But remnants of four ballistic missiles fired into Saudi Arabia by the Houthis on May 19, July 22, July 26 and November 4, 2017 appear to have been designed and manufactured by Iran, according to a confidential U.N. report from November 2017.
"The United States welcomes this report, as should every nation concerned about Iranian expansion," U.S. ambassador to the United Nations Nikki Haley said on December 14, in front of the remains of a missile allegedly fired by the Houthis into Saudi Arabia. "It was made in Iran, then sent to Houthi militants in Yemen. From there it was fired at a civilian airport, with the potential to kill hundreds of innocent civilians in Saudi Arabia."
Iranian officials and Houthi leaders denied U.S. claims. "After three years of war, America suddenly finds evidence that Iran supports the Houthis," a Yemeni spokesman said, according to Reuters. "America did not find any evidence in all the missiles fired from Yemen until now. The story is clear. They want to give Arabs a story to divert their attention from Jerusalem. Instead being angry at Israel, they wave the Iranian boy," he added.
While #Iran has been calling for ceasefire, aid and dialogue in #Yemen from day 1, US has sold weapons enabling its allies to kill civilians and impose famine.

On December 21, the U.S. State Department echoed Haley's allegations. "There is a very key relationship between the Iranians and the Houthis," Tim Lenderking, deputy assistant secretary for Near Eastern Affairs, said. "I don’t want to overstate it. I don’t want to suggest that the Houthis operate entirely at the behest of the Iranians. But it’s an important relationship and one that the Iranians are able to exploit." Lenderking encouraged reporters to visit the display of missile remains and other military equipment that Haley highlighted the previous week.
In January, a U.N. report concluded Iran had violated an arms embargo by failing to prevent the Houthis from obtaining Iranian missiles. Iran did not comment on the U.N. panel report, but Iranian foreign minister Javad Zarif denied U.S. claims of Tehran's missile support once again in a series of tweets in late January 2018.
A while ago US showed a Saudi-supplied Iranian missile intact. They must've been told a missile destroyed by a Patriot does not land fully assembled.

Less than two weeks later, however, Houthi spokesman Mohammad Abdul Salam met with Zarif in Tehran. Abdul Salam updated Zarif on the current conditions in Yemen. Zarif outlined Iran's four-point peace plan for Yemen and stressed the need for an immediate end to the war. He also called for the immediate shipment of humanitarian aid to Yemeni civilians.
In mid-February, the United States, Britain, and France drafted a UN resolution that condemned Iran for violating the Yemen arms embargo by failing to prevent the Houthis from obtaining Iranian missiles. Russia vetoed the resolution.

The Houthis stepped up their attacks on Saudi Arabia in the following months. In late March, the rebels fired seven missiles at Saudi Arabia in one night and resulted in the of an Egyptian resident. A few weeks later, they struck a Saudi oil tanker in international waters west of Yemen's Hodeidah port.
A mid-April missile targeting the Saudi capital Riyadh prompted a U.S. response. The State Department condemned the attack and blamed Iran for its alleged Houthi support. "We support the right of our Saudi partners to defend their borders against these threats, which are fueled by the Iranian regime’s dangerous proliferation of weapons and destabilizing activities in the region," said State Department spokesperson Heather Nauert.

The Houthis have other sources of support, however. They have reportedly received funding from local supporters and sympathetic charities as well as from illegal trade.
What are the Houthis' political views?
What are the roots of the Houthis' conflict with the central government?
How did the Houthis rise to power?
What is the relationship between Houthis and other Islamists in Yemen?
The Houthis have a tense relationship with Islah, a Sunni Islamist party with links to the Muslim Brotherhood. Islah claims the Houthis are an Iranian proxy, and blames them for sparking unrest in Yemen. The Houthis, on the other hand, have accused Islah of cooperating with al Qaeda in the Arabian Peninsula (AQAP).
After the Houthis took over Sanaa in September 2014, Islah initially took a few steps towards reconciliation. In November, top Islah and Houthi leaders met to discuss a political partnership. Islah called on the Houthis to cease attacks on Islah members and to release Islah prisoners. In December, the United Nations and Gulf Cooperation Council brokered a deal between the two groups to cease hostilities.
But clashes between the Houthis and Islah continued. In the first four months of 2015, the Houthis kidnapped dozens of Islah party leaders and raided their offices. By April, more than 100 Islah leaders were detained by the Houthis. Tensions increased after Islah declared support for the Saudi-led airstrikes.
The Houthis are also at odds with Sunni extremist groups. On March 20, 2015, an ISIS affiliate calling itself the Sanaa Province claimed responsibility for suicide bomb attacks on two Zaydi mosques that killed at least 135 people and injured more than 300 others. The group issued a statement that said “infidel Houthis should know that the soldiers of the Islamic State will not rest until they eradicate them.”
AQAP denied involvement in the mosque attacks, but has frequently targeted the Houthis. In April 2015, the group claimed responsibility for three suicide attacks that killed dozens of Houthis in Abyan, al Bayda’, and Lahij. AQAP has reportedly partnered with southern tribes to fight the Houthis.
Who are their leaders?
Abdul Malik al Houthi, brother of Hussein al Houthi, has been the group’s spiritual, military, and political leader since 2007. Little is known of his personal life, and he makes few public appearances. His brother-in-law, Youssef al Midani, is the deputy leader. Abdul Malik’s two brothers, Yahia and Abdul-Karim, are also senior leaders of the movement.
On April 14, 2015 the U.S. Treasury imposed sanctions on Abdul Malik al Houthi for engaging in acts that “threaten the peace, security, or stability of Yemen.” The same month, the U.N. Security Council imposed an arms embargo against the Houthis and blacklisted Abdul Malik al Houthi.
