In 2008 I went to Yemen to check on the remaining Jews of Yemen. One of the oldest Jewish communities that holds to its traditions. There are 3 main Jewish communities: Ashkenazim, Sephardi and Yemenite. There were less then 200 left in Yemen and the majority at that time were running from the Huties to Sanaa.
If there are any today (2021) it will be a miracle.
