People gather at the site of an air strike at a residential area near Sanaa Airport, March 26.

SANAA — Yemen’s President Abd-Rabbu Mansour Hadi left his refuge in Aden for Saudi Arabia on Thursday as Houthi rebels battled with his forces on the outskirts of the southern port city.

Throughout the day, warplanes from Saudi Arabia and Arab allies struck at the Houthis and allied army units, who have taken over much of the country and seek to oust Hadi.

Warplanes resumed bombing the Houthi-held capital Sanaa on Thursday evening, shaking whole neighborhoods and terrifying residents. Several civilians have been reported killed in Sanaa.

“My whole family and I are preparing to sleep in the basement, as it’s the safest part of the house,” said resident Fawzia Nedras. “The windows are rattling and we think they may break. We live near the airport, where we think a lot of the Houthi leaders are living and many of the air strikes are.”

Houthi leader Abdel-Malek al-Houthi said in a televised speech Yemenis would confront the “criminal, unjust and unjustified aggression” by Saudi Arabia.

Residents and security officials said the second night of air strikes throughout Yemen targeted air and ground force bases loyal to ex-president Ali Abdullah Saleh, whose forces have bolstered the Houthi advance.

The Saudi-led military intervention marked a major escalation of the Yemen crisis, in which Iran supports the Houthis and monarchies in the Gulf back Hadi.

Iran denounced the surprise assault on the Houthis and demanded an immediate halt to Saudi-led military operations.

Tehran also made clear Saudi Arabia’s deployment of a coalition would inflame the sectarian hatreds already fueling wars around the Middle East.

Hadi’s departure under Saudi protection from Aden, his embattled base since fleeing Sanaa in February, could be a turning point.

Saudi state news showed pictures of Hadi smiling and holding hands with the Saudi defense minister receiving him at an airport in the capital Riyadh and said he would go on to Egypt to attend an Arab summit on Saturday.

Mohammed Marem, the director of Hadi’s office, confirmed he would attend the meeting in person, dropping his original plan to address it via video link.

Hadi would seek a “Marshall Plan” from Arab leaders to aid his war-torn country, his foreign minister Riyadh Yaseen told pan-Arab Al Jazeera TV, referring to a major economic stimulus for Europe after World War II.

It was far from certain whether Hadi would be able to return to Aden.

On the city’s northern outskirts, Houthis and allied troops fought gun battles with militiamen loyal to Hadi. Thirteen pro-Houthi fighters and three militiamen were killed and several others were killed in running street fights in nearby towns.

Pro-Hadi fighters retook Aden airport a day after it was captured by Houthi forces. The facility remained closed.

Major gamble

The Saudi move was a major gamble by the world’s top oil exporter to check Iranian influence in its backyard without direct military backing from Washington.

“We will do whatever it takes in order to protect the legitimate government of Yemen from falling,” Saudi Arabia’s ambassador to the United States, Adel al-Jubeir, told a news conference in Washington.

In Sanaa, which the Houthis seized in September, warplanes earlier bombed the main airport and al Dulaimi military air base, residents said.

A Reuters witness said four or five houses had been damaged. Rescue workers put the death toll at 13, including a doctor pulled from the rubble of his clinic.

Warplanes also struck Houthi fighters near Yemen’s border with Saudi Arabia, tribal and Houthi sources said. There was heavy street fighting in Houta, north of Aden, in which five pro-Houthi fighters and four militiamen were killed.

Thousands of Houthi supporters gathered to condemn the air strikes at the gate to Sanaa’s old city, waving Houthi banners and chanting “Death to America!”

Al-Arabiya said Saudi Arabia was contributing 100 warplanes to operation “Storm of Resolve” and more than 85 were being provided by the United Arab Emirates, Qatar, Bahrain, Kuwait, Jordan, Morocco and Sudan.

Egyptian air forces were participating and four naval ships headed to secure the Gulf of Aden. Turkey said it might provide logistical support.

Turkish President Tayyip Erdogan said later Iran had been trying to dominate the Middle East.

“It is really not possible to tolerate this. Iran has to understand,” he said, adding Tehran should withdraw any forces it had in Yemen as well as from Syria and Iraq.

Pakistan’s Prime Minister Nawaz Sharif said any threat to Saudi Arabia would “evoke a strong response” from Islamabad.

Pakistan, which borders eastern Iran, said it was considering a Saudi request that it send troops to Yemen.

Saudi Brigadier General Ahmed Asseri, spokesman for the operation, told a news conference: “There are no plans at this stage for ground forces operations, but if the need arises, the Saudi ground forces and those of the friends and sisterly forces are ready and will repel any aggression.”

Russian President Vladimir Putin called for an immediate cessation of military activities in Yemen in phone conversations with Iran’s President Hassan Rouhani, the Kremlin said.

U.S. Secretary of State John Kerry raised Yemen on Thursday with his Iranian counterpart before turning to nuclear negotiations in Switzerland.

Iran and Hezbollah condemn

Iran’s Foreign Ministry demanded an immediate halt to the “aggression and air strikes” in Yemen.

“Military actions in Yemen… will further complicate the situation,” ministry spokeswoman Marzieh Afkham said, quoted by Fars news agency.

A senior Iranian official said; “Iran will use all possible political ways to allay tension in Yemen. Military intervention is not an option for Tehran.”

Riyadh accuses Iran of stirring up sectarian strife throughout the region and in Yemen with its support for the Houthis. Iran denies funding and training the Houthis.

Lebanon’s Hezbollah, which is supported by Iran and backs the Houthis, condemned as “unwise” and “illegitimate” the military intervention in Yemen, calling for an immediate halt to the airstrikes.

“Hezbollah strongly condemns the Saudi-U.S. aggression targeting the brotherly people of Yemen, its national army and its vital installations,” the party said in a statement.

It also denounced the participation of some Arab and non-Arab countries in “this aggression and providing it with political cover.”

“This Saudi-led adventure, which lacks wisdom and legal and legitimate justifications, is taking the region toward increased tension and risks the future and the present of the region,” the statement said. “We see that this aggression secures U.S. interests and does a great favor for the Zionist enemy.”

Hadi requested the intervention

Ambassador Jubeir said the assaults were in response to a request by Hadi. Washington said it supported the operation and had authorised U.S. logistical and intelligence support.

A widening Yemen conflict could disrupt the narrow Bab el-Mandeb strait, through which nearly 4 million barrels of oil are shipped daily to Europe, the United States and Asia. 

Yemen closed its main ports. The U.S. military said it would help ensure the strait at the tip of the Red Sea remains open.
