Saudi-led airstrikes in Yemen will continue until Shia rebels there "withdraw and surrender their weapons," a summit of Arab leaders decided Sunday, as they also agreed in principle to forming a joint military force.
The decision by the Arab League puts it on a path to more aggressively challenge Iran, which they accuse of backing the Yemeni rebels, known as Houthis.
A Saudi-led coalition began bombing Yemen on Thursday, saying it was targeting the Houthis and their allies, which include forces loyal to Yemen's former leader Ali Abdullah Saleh. Current and former Yemeni military officials have said the campaign could pave the way for a possible ground invasion.
At the summit, held in the Egyptian resort city of Sharm el-Sheikh, Arab League chief Nabil Elaraby read a final communiqué outlining the leaders' views.
"Yemen was on the brink of the abyss, requiring effective Arab and international moves after all means of reaching a peaceful resolution have been exhausted to end the Houthi coup and restore legitimacy," Elaraby said.
The Houthis swept down from their northern strongholds last year and captured the capital Sanaa in September. Embattled President Abed Rabbo Mansour Hadi, a close U.S. ally against a powerful local Al-Qaeda affiliate, fled first to the southern city of Aden before leaving the country last week.
Speaking at the summit on Saturday, Hadi directly accused Iran of being behind the Houthi offensive, raising the specter of a regional conflict. Iran and the Houthis deny that Tehran arms the rebel movement, though the Islamic Republic has provided humanitarian and other aid.
Asked at a news conference to explain vague references to "foreign powers" being behind conflicts in different Arab nations, Elaraby said: "I will answer this question indirectly. There is meddling by some neighbors, Israel on one side, Turkey and Iranian interference in several countries."
Speaking after Elaraby, Egyptian President Abdel Fatteh El Sisi said leaders also agreed in principle to creating a joint Arab military force. He said a high-level panel would work under the supervision of Arab chiefs of staff to determine the structure and mechanism of the force.
Elaraby said the chiefs of staff would meet within a month and have three more months to decide on the structure, budget and mechanism of the force before they present their proposals to a meeting of the Arab League's Joint Defense Council.
"It is an important resolution given all the unprecedented unrest and threats endured by the Arab world," Elaraby said.
A summit resolution said the force would be deployed at the request of any Arab nation facing a national security threat and that it would also be used to combat terrorist groups.
"There is a political will to create this force and not to leave its creation without a firm time frame," Egyptian Foreign Minister Sameh Shukri told a news conference.
Egyptian military and security officials have said the proposed force would consist of up to 40,000 elite troops and be headquartered in either Cairo or Riyadh, the Saudi capital. The force would be backed by jet fighters, warships and light armor.
However, it is unlikely that all 22-member nations of the often-fractious Arab League will join the proposed force. Creation of such a force has been a longtime goal that has eluded Arab nations in the 65 years since they signed a rarely used joint defense agreement.
Iraq, whose Shia government is closely allied with Iran, has said more time is needed to discuss the proposed force.
The Saudi-led air campaign has pushed Houthi rebels out of contested air bases and destroyed any jet fighter remaining in Yemen, said Saudi Brig. Gen. Ahmed bin Hasan Asiri.
Fierce fighting has been reported in Yemen's coastal city of Aden as Houthi continued their push south despite a fifth night of Saudi-led airstrikes against the group's positions.
Clashes were reported in the Dar Saad district of Aden on Sunday as fighters loyal to Hadi battled Houthis trying to push their way to the city's northern gate.
Hadi loyalists said they had recaptured the airport, which has changed hands several times in recent days, as a gun battle raged in Aden's central Crater district.
Nearly 100 people are reported to have been killed in the violence in Aden.
Heavy fighting was also reported in Shabwa province, with local tribes in Beihan saying that at least 40 Houthi fighters were killed in battles there.
The strikes also continued to target Scud missiles in Yemen, leaving most of their launching pads "devastated," according to remarks carried Saturday by the state-run Saudi Press Agency. However, Asiri warned that the rebels could have more missiles. His account could not be immediately corroborated.
Yemen's Foreign Minister Riad Yassin said the air campaign, codenamed Operation Decisive Storm, had prevented the rebels from using planes they seized to attack Yemeni cities or missiles to attack neighboring Saudi Arabia. It also stopped Iran's supply line to the rebels, he said.
Yassin said military experts would decide when and if a ground operation is needed.
"This is a comprehensive, a package operation and (ground operations) will depend on the calculations of the military," he told reporters. Yassin said political dialogue would only happen after the Houthis surrender the weapons they seized from the state.
