In the first reported use of a ballistic missile in the conflict, the Scud was fired on Saturday morning at the city of Khamees Mushait in the kingdom’s southwest and was intercepted by two Patriot missiles, a statement by the Saudi military said.
The area is home to the largest air force base in southern Saudi Arabia, the world’s top oil exporter, but there are no oil facilities in the vicinity.
Al Masira, the Houthi group’s official channel, confirmed the launch and said it targeted the King Khaled air base.
An alliance of Gulf Arab nations has been bombing Yemen’s Houthi militia and allied army units loyal to powerful ex-President Ali Abdullah Saleh since March 26 in an attempt to restore exiled President Abd-Rabbu Mansour Hadi to power.
Saturday’s violence came despite progress toward United Nations-backed peace talks planned for Geneva this month, to which both the exiled government and the Houthis have agreed.
The coalition has said a main goal of its war effort is to neutralize the threat that rockets in Yemen pose to Saudi Arabia and its neighbors.
The alliance’s spokesman, Saudi Brigadier General Ahmed Asseri, said in April that it had removed the threat from heavy weapons. He later appeared to step back from that assertion, saying that 80 percent of the 300 or so missiles had been destroyed – a figure he repeated on Saturday.
Asseri told the Saudi-owned Arabiya TV channel that the Houthis and their allies took advantage of a five-day humanitarian ceasefire ending on May 17 to position the arms.
“These militias succeeded during the five-day truce in moving the rockets being targeted, and the one fired today was one of those,” Asseri said.
“Praise God, we have air defense forces capable of blocking these kinds of rockets, destroying them and thwarting attempts like this,” he added.
The Houthis at the time denied Saudi and American accusations that it used the pause to transport weaponry.
The Sunni Muslim coalition states fear the Houthi movement, from a Shi’ite sect in north Yemen, will act as a proxy for their arch-rival in the region, Shi’ite Iran.
Iran and the Houthis deny any military or economic links, and the Houthis say their seizure of the capital Sanaa in September and their advance southward is part of a revolution against a corrupt government.
BORDER BATTLE
Arab air strikes have pounded arms and missile stores in the capital Sanaa and other military bases in Yemen almost daily.
The 11-metre-long (35-foot) Scuds have ranges of 300 km (200 miles) and more. The Cold War era ordnance has been used in internal conflicts in Syria and Libya and was fired by Saddam Hussein’s Iraq at Saudi Arabia in the 1991 Gulf War.
Saleh, Yemen’s autocrat president from 1978 to 2012, was forced to step down amid Arab Spring street protests but retains most of the army’s loyalty and has joined forces with the Houthis in combat with Hadi’s armed backers in Yemen’s south.
His forces traded Scud missile fire with southern separatists in a 1994 civil war.
Al Arabiya TV described overnight ground fighting along the border as the “largest attack” yet by Houthi forces and Yemen’s republican guard, a unit close to Saleh.
“It was the first confrontation undertaken by Saleh’s (Republican) guard, and coalition planes and Saudi Apache (helicopters) undertook ground fire for 10 hours,” said Al Arabiya’s correspondent in the southern Jizan region.
Hamed al-Bukhaiti, a Houthi spokesman, indicated that the group had embarked on an escalation along the border. “We’ve only just begun, and next time will be stronger,” he said on his Twitter page.
The options are open and the battle has begun to block the aggression on Yemen … this is the battle the people of Yemen have been awaiting,” he wrote.
Saudi-led forces said on Friday that four Saudi soldiers, including two officers, were killed after an attack was launched from the Yemeni side on border areas in Jizan and Najran.
Thirteen people were killed on Saturday and dozens were wounded in an Arab air strike on a camp for displaced people in Hajja province along Yemen’s border with Saudi Arabia, the Houthi-controlled state news agency Saba said. The report could not be independently verified.
Residents in the southern city of Aden said heavy artillery battles resumed after a pause of several days on Saturday, in clashes which killed around 10 Houthi fighters and three pro-Hadi militiamen.
Ahead of the U.N. peace talks, a Houthi delegation left on Saturday for talks in Russia on the situation in Yemen, Houthi official Daifallah al-Shami said, without providing details.
Russia was the only country in the 15-member United Nations Security Council that abstained from a resolution in April calling on the group to recognize Hadi’s authority and quit Yemen’s main cities.
