Thirty-one people were killed in airstrikes on Yemen on Saturday, the United Nations says, the victims of an apparent Saudi-led retaliation after Iran-backed Houthi rebels claimed to have shot down one of Riyadh's jets.
The Tornado aircraft came down on Friday in northern Al-Jawfprovince during an operation to support government forces, a rare shooting downthat prompted operations in the area by a Saudi-led military coalition fightingthe rebels.
The deadly violence follows an upsurge in fighting in northern Yemen between the warring parties that threatens to worsen the war-battered country's humanitarian crisis. "Preliminary field reports indicate that on 15 February as many as 31 civilians were killed and 12 others injured in strikes that hit Al-Hayjah area in Al-Jawf governorate," the office of the UN humanitarian coordinator for Yemen said in a statement. Lise Grande, the UN coordinator, denounced the "terrible strikes".
"Under international humanitarian law, parties which resortto force are obligated to protect civilians," she said. "Five years into thisconflict and belligerents are still failing to uphold this responsibility. It'sshocking."
The rebels reported multiple coalition airstrikes in the area where the plane went down, adding that women and children were among the dead and wounded, according to rebel television station Al-Masirah. The coalition conceded the "possibility of collateral damage" during a "search and rescue operation" at the site of the jet crash, which left the fate of its crew uncertain.
Without stating the cause of the crash, a coalitionstatement released by the official Saudi Press Agency said the crew of twoofficers ejected from the plane before it crashed but the rebels opened fire atthem in "violation of the international humanitarian law".
"The lives and wellbeing of the crew is the responsibilityof the terrorist Houthi militia," the statement said, without saying whetherthey had survived.
The Houthi rebels released footage of what they called thelaunch of their "advanced surface-to-air missile" and the moment it struck thejet in the night sky, sending it crashing down in a ball of flames.
"The downing of a Tornado in the sky above Al-Jawf is amajor blow to the enemy and an indication of remarkable growth in Yemeniair defence capabilities," Houthi spokesman Mohammed Abdelsalam tweeted.
The escalation follows fierce fighting around the Houthi-held capital, Sanaa, with the rebels seen to be advancing on several fronts towards Al-Hazm, the regional capital of Al-Jawf. The province of Al-Jawf has been mostly controlled by the Houthis, but its capital remains in the hands of the Saudi-backed government. The downing of a coalition warplane marks a setback for a military alliance known for its air supremacy and signals the rebels' increasingly potent military arsenal.
"At the start of the conflict the Houthis were a ragtag militia," said Fatima Abo Alasrar, a scholar at the Middle East Institute. "Today they have massively expanded their arsenal with the help of Iran and its proxy Hezbollah."
