Afghan Voice Agency (AVA): The Times newspaper, published by the Israeli regime, wrote: Kogan, a rabbi of the Chabad movement, had been missing in the UAE since Thursday.
The statement said that the Israeli embassy in Abu Dhabi has been in contact with Kogan's family in the UAE.
Tel Aviv called the murder "a despicable anti-Semitic terrorist act" and pledged to use all available means to bring the killers to justice.
Kogan was a dual Israeli-Moldovan citizen.
