A fuel shortage in Yemen is hampering the movement of people fleeing the country’s escalating fighting and seeking safety across the Red Sea in Djibouti, with the UN migration agency warning that more Yemenis are ready to make the crossing by boat. More than 2,000 Yemenis are currently in Djibouti, where the country's government and the International Organization for Migration are providing food and shelter. Yemen’s legitimate government has been battling the Iranian-backed Houthi militants for 12 years. The recent escalation has ended a ceasefire that had largely stopped civil war across Yemen since 2022. The Houthis kept to the sidelines during the initial, heavy phase of the Iran war, but in July they resumed attacks on Saudi Arabia and escalated attacks in Yemen. Now the number of people from Yemen fleeing the fighting is soaring, with nearly 94,000 people displaced in the country. IOM Regional Director for East and Southern Africa Frantz Celestin told The Associated Press on Monday that arrivals had slowed because of the fuel shortage, but warned that more people were expected to make the dangerous crossing. “We expect more to come. What we were told is that there are a lot of people who are willing and ready to come. They simply don’t have fuel to make the journey,” Celestin said. “There’s a fuel shortage in Yemen that may explain the lull that we’ve seen today.” The prospect of more arrivals is raising concerns that Djibouti, the small Horn of Africa nation, could struggle to accommodate the influx. “When you have that many people come in a short amount of time, it’s bound to overwhelm the system,” Celestin said. “But so far, they (Djibouti) are managing it quite well. But there may be a time, if they continue to come, where they may overwhelm the capacity of the country to house and accommodate all of them.” Djiboutian Finance Minister Ilyas M. Dawaleh said on X that the situation was “becoming increasingly difficult for our country, despite our unwavering commitment to humanitarian assistance.” “We cannot allow those who have sought refuge among us to suffer. I am proud of my fellow Djiboutians for their collective mobilization and their remarkable solidarity with our Yemeni brothers and sisters,” he wrote. Dawaleh also praised residents of Obock, a coastal town in northern Djibouti that has been on the front line of the humanitarian response. The IOM's Celestin said the arrivals were putting additional pressure on communities and called for more international support, including additional tents and medical services. Djibouti sits across the Bab al-Mandeb Strait from Yemen, making it one of the closest places of refuge for Yemenis fleeing the conflict.
