For Imad and his sister Alia, life will never be the same after their father was killed by a landmine and they had to leave their endangered home in Yemens western Hodeidah province, said an Agence-France Presse report on Tuesday. With their house surrounded by the deadly munitions, the two children and their mother, left Al-Dunain village and headed for shelter at the Al-Waara camp in the Khokha district, some 30 kilometers (18 miles) from the town of Hays. Withdrawing Iran-backed Houthi militias have dotted the area with mines, their mother Fethiyeh Fartout said. And it was while her husband made his way to market that he was killed on a road "riddled with landmines". "The Houthis then told us to either leave the house or risk being killed," she told AFP. The Houthis have been accused of widespread and indiscriminate use of landmines. Yemen is a signatory to the international Mine Ban Treaty, which came into force in 1999, and aims to eliminate landmines and clear up vast tracts of polluted land. And indiscriminate use of landmines is deemed a war crime by international bodies. While the Houthis have made no media comments about landmines, in a letter to Human Rights Watch (HRW) in 2017 the Houthis’ illegitimate foreign ministry in Sanaa denied using landmines or having stockpiles. But for Fartout and her children there is no way to return home, even if they tried, said her father Jamal Fartout. "The Houthis planted landmines everywhere, and their explosives destroyed the roads," he told AFP. "All the roads leading back to our home are lined with explosives." HRW said in June that landmines in Yemen were hindering aid access and entrapping people. "Houthis have repeatedly laid antipersonnel, anti-vehicle and improvised mines as they withdrew from areas in Aden, Taiz, Marib and, more recently, along Yemens western coast," the HRW said. Landmines "will pose a threat to civilians long after the conflict ends," it warned. In July, the Washington Institute said that, while landmines have plagued Yemen for decades amid different conflicts, the Houthis are using them today "at an astonishingly high rate." While exact numbers are "notoriously difficult to verify", the institute said one "Yemeni de-mining official claims the Houthis have laid 500,000 mines since 2015" while de-mining teams "have reportedly removed 300,000 landmines". The non-governmental Landmine and Cluster Munition Monitor recorded more than 2,100 casualties in Yemen from landmines in 2016. "I asked the Houthis, where can we go when the breadwinner of the family was killed by a landmine?," Fartout said. Hundreds of people now live in make-shift tents in Al-Waara – partly funded by the United Arab Emirates (UAE). While dozens of children, some barefoot, run around the camp, one boy sits in a wheelchair -- his leg in a cast. He, too, was a victim of a landmine. In June, Saudi Arabia launched a new project for landmine clearance in Yemen, but "landmines will remain a formidable challenge in the postwar era," the Washington Institute added.
