A Yemeni rebel missile attack on an airport in southwestern Saudi Arabia injured 26 civilians on Wednesday, drawing promises of "stern action" from the Saudi-led coalition fighting the rebels.
Yemen's Huthi rebels, who have faced persistent coalition bombing since March 2015 that has exacted a heavy civilian death toll, have stepped up missile and drone attacks across the border in recent weeks.
Wednesday's missile strike hit the civil airport in the mountain resort of Abha, which is a popular summer getaway for Saudis seeking escape from the searing heat of Riyadh or Jeddah.
Eight of the wounded were admitted to hospital, coalition spokesman Turki al-Malki said.
The other 18 were discharged after receiving first aid, he added in a statement carried by the official Saudi Press Agency.
The missile caused some damage to the airport's arrivals lounge and flights were disrupted for several hours before returning to normal.
Malki said at least one Indian was among three women wounded along with two Saudi children.
Malki said the strike on the airport amounted to a "terrorist attack" on a civilian target which could be considered a "war crime."
He said the coalition would "take stern action" to deter the rebels and protect civilians.
The rebels confirmed they had launched a missile at Abha airport but insisted they had the right to defend themselves in the face of more than years of Saudi-led bombing. and air and sea blockade.
"The continuation of the aggression and siege on Yemen for the fifth year, the closure of Sanaa airport and the rejection of a political solution make it inevitable for our people to defend themselves," Huthi spokesman Mohammed Abdulsalam said in a statement reported by the rebels' Al-Masirah television.
There has been a spate of cross-border attacks by the rebels in recent weeks which have coincided with reports of intensified coalition strikes on rebel strongholds on the other side of the border.
On Monday, Saudi air defenses intercepted two rebel drones headed for Khamis Mushait.
The city, not far east of Abha, houses a major airbase that has been one of the main launchpads for the coalition's bombing campaign in Yemen.
Last month, the Saudi air force shot down a rebel drone that targeted Jizan airport, on the Red Sea coast close to the Yemeni border, the coalition said.
The rebel attacks come as Saudi state media reported the coalition was intensifying its air raids on rebel positions in the northern Yemeni province of Hajjah.
In May, the rebels also carried out twin drone attacks on the kingdom's strategic east-west oil pipeline, forcing a two-day closure of the main diversionary route for Saudi exports avoiding the Gulf.
Riyadh accused its regional arch foe Iran of having a hand in that attack and it leveled a similar allegation over the airport strike.
The coalition spokesman said the missile hit "proves this terrorist militia's acquisition of new advanced weapons and the continuation of the Iranian regime's support and waging of cross-border terrorism."
The uptick in violence comes as a U.N.-led peace push falters despite the rebels' unilateral withdrawal from the lifeline Red Sea port of Hodeida last month.
The Yemeni government has accused U.N. envoy Martin Griffiths of bias towards the rebels despite the Security Council's expression of renewed support in him on Monday.
The coalition intervened in support of the Yemeni government in 2015 when President Abedrabbo Mansour Hadi fled into Saudi exile as the rebels closed in on his last remaining territory in and around second city Aden.
Since then, the conflict has killed tens of thousands of people, many of them civilians, relief agencies say.
It has triggered what the U.N. describes as the world's worst humanitarian crisis, with 24.1 million -- more than two-thirds of the population -- in need of aid.© 2019 AFP
