Hundreds of mourners gathered on Monday in the pouring rain for a ceremony ahead of the funeral of an Israeli-Moldovan rabbi who was killed in the United Arab Emirates. The UAE said Monday police arrested three Uzbek nationals following the death of Zvi Kogan,

As authorities investigate who is responsible for Kogan’s death, political circles in Washington, D.C., Israel, and the Gulf are asking a related question: What will this do to UAE-Israel ties?

Zvi Kogan, 28, an ultra-Orthodox rabbi, ran a kosher grocery store in Dubai, where Israelis have flocked for commerce and tourism.
