A mysterious air base is being built on a volcanic island off Yemen

While no country has claimed the Mayun Island air base in the Bab el-Mandeb Strait, shipping traffic associated with a prior attempt to build a massive runway across the 5.6-kilometer (3.5 mile)-long island years ago links back to the United Arab Emirates. Officials in Yemen’s internationally recognized government now say the Emiratis are behind this latest effort as well, even though the UAE announced in 2019 it was withdrawing its troops from a Saudi-led military campaign battling Yemen’s Houthi rebels.
