Israel and the United States are working to prevent members of the extremist "Lev Tahor" ultra-Orthodox sect from moving to Iran. The fear is that Tehran will use them as a bargaining chip for future negotiations.
Members of the Lev Tahor group, which is anti-Zionist, applied for political asylum in Iran in 2018. Documents filed in a US federal court showed that the leaders of the Hasidic cult swore allegiance to Supreme Leader Ayatollah. Ali Khamenei.
According to the Ynet news site, hundreds of members of the group, mainly based in Guatemala, may be trying to move to Iran after dozens of families were seen at the airport in Guatemala, en route to Kurdistan, the border between Iraq and Iran.
