A Houthi ballistic missile attack on a mosque and a religious school killed 29 civilians, including women and children, in the <a href="https://www.thenationalnews.com/tags/yemen/" target="_blank">Yemeni</a> province of Marib, the country's information minister said on Monday. "Once again, the Iranian-backed Houthi militia targets residential communities in Al Juba district, south of Marib governorate, this time with two 'Iranian-made' ballistic missiles that hit a mosque and Dar Al Hadith in the overcrowded area of Al Amoud and displaced families from outside the district, killing 29 civilians, including women and children," said Moammar Al Eryani on Twitter. There was no immediate claim of responsibility by the <a href="https://www.thenationalnews.com/tags/houthis/" target="_blank">Iranian-backed Houthis</a>. Fighting between government forces and Houthis has escalated in recent months. The UN said about 10,000 people were displaced in September by fighting in Marib, the internationally recognised government's last northern stronghold. It is calling for a <a href="https://www.thenationalnews.com/gulf-news/2021/10/29/aid-agencies-call-on-yemens-warring-sides-to-save-civilians-in-marib/" target="_blank">humanitarian corridor for aid.</a> Two ballistic missiles were used in the attack late on Sunday, the Marib governor's office said. The war in Yemen, the ensuring economic collapse and restrictions on imports to Houthi-held areas have resulted in what the UN describes as the world's biggest humanitarian crisis, with 16 million people facing starvation. A coalition of forces led by Riyadh intervened in Yemen in March 2015 after the Houthis ousted the Saudi-backed government from the capital Sanaa in late 2014. The Houthis, which claim to be fighting a corrupt system and foreign aggression, seized new territory in the energy-rich provinces of Shabwa and Marib in October – the gains of which were confirmed by officials – as they press forward with an offensive that is expected to further complicate international peace efforts. Seperatly, the UAE on Monday condemned the recent <a href="https://www.thenationalnews.com/gulf-news/2021/11/01/uae-condemns-booby-trapped-drone-launched-by-houthis-towards-khamis-mushait/" target="_blank">Houthi targeting of civilians in the Saudi city of Khamis Mushait</a> with explosive drones.
