A retired Israel Defense Force colonel who had consulted for the Cameroonian military was killed in a helicopter crash in western African republic on Monday.
Colonel (ret.) Avi Sivan was a military advisor to Cameroon's president, in charge of, among other duties, training a presidential-guard brigade.
Sivan had been one of the founders of the elite IDF unit Duvdevan, later becoming the head of the Defense Ministry's delegation to Cameroon.
Following his retirement from public service, Sivan then turned to the private sector as a security advisor.
Sivan had business ties with Israeli Sami Meyuhas, who, up until ten years ago, was the only person with the Defense Ministry's permission to export Israeli security goods.
A decade ago Meyuhas' exclusivity was revoked, with the Israeli businessman continuing to work within Cameroon as the representative of both Israel and foreign companies.
Israel made an official appeal to the Cameroonian government to retrieve Sivan's body for burial in Israel.
